cannot calculate the route No roads near starting point

Just curious. You have had quite a bit of problems with this unit i see. Do you have Legal Maps on your unit? I've seen this before when one gets cracked Maps on the net and installs them.

You've already confirmed elsewhere that you've checked your 465T's Map Info page and you see City Navigator there AND that it's CHECKED. An unchecked City Navigator is the most common problem that can cause your issue.

I'm unsure as to the error file. Can you connect your nuvi to a computer and run WebUpdater to confirm that you have the latest firmware, etc?

gmapbmap is the Basemap which will show you a few roads and streets but is not routable. If you see a small number of streets and can do no routing anywhere, then the gmapbmap files are probably OK.

For US folks with a nuvi using City Navigator maps and map updates, gmapprom.img is the City Navigator image file. It is a big file. There also needs to be a gmapprom.unl file (and there is likely a gmapprom.sum file but it's not important here). Assuming you have the latest map update, 2013.30, your gmapprom.img file should be 1,877,152KB in size (unless the trucker's file is a different size or that trucker's map updates include additional files).

Assuming City Navigator is checked on your map info page on the nuvi, the next step is to see that you have both gmapprom files and that the big .img file is the right size.

It's possible that your map file is corrupt and not able to be displayed which forces you to see only the Basemap which can't be used for routing. The fix for a corrupt file is to redownload the map to your nuvi: with the nuvi connected to your computer, sign into myGarmin, then go to the myMaps tab and you should be given the option to reinstall the current map. Make sure that your computer will not go to sleep during the download and installation, especially since you mentioned an 8-hour download at one point. And the end of the installation, Eject or Safely Disconnect your nuvi rather than just pulling the cable. And never pull or install a SD card to your nuvi while the nuvi is on.

Another question: did this issue arise out of the blue--or did it start right after a map update or firmware update or some such thing? You said elsewhere that you have lifetime map updates for this unit and these problems seemed to arise after your attempts to do a map update. Did you do any tinkering--i.e., deleting--files on the 465T while trying to update your map and possibly delete an essential file?

One last question: is your map installed to the nuvi's internal storage or to a SD card? I wasn't clear on this in your past posts. If it's on a SD card, you could have a defective SD card or bad connection between the card and the nuvi. A lot of folks including me swear by SanDisk cards and for this use, a 4 or 8GB Class 4 card will do well and they are easy to find and pretty cheap these days.

Good luck and shout back with your results. Bummer to have a non-working nuvi, huh, especially if driving a big rig of one sort or another?

Googling around with your error message, it may indicate an error in the firmware. If WebUpdater doesn't help, a call to Garmin Tech Support may be your next step.

It would be nice if you had the ability to try a map update without using a slow Verizon MiFi card. Is there any chance you could use someone's computer with their faster broadband access to the net?

HI..fair question.. Not my style to beat someone out of a few bucks for anything... Yes my maps are legal.. I have lifetime updates for my 465T. Christmas present in 2011.. The problem is not there initially, then I go approx 1 mile and shazam no more map... The voice keeps telling me directions.

When I can get to a high speed connection I will DL the latest maps..

If you have any suggestions, please let me know.

Thanks..

CraigW.. Hi... I dbl checked and my City Nav map was NOT checked.

Just put in a destination and it appears to be working..

So will continue to read thru your analysis and suggestions.

Many thanks for your input and sensitivity.

Well done. My guess now is that all is well with your nuvi and you can ignore everything else I've said

I wouldn't ignore this info, perhaps another wiki help page should be assembled.

HI ...Still not up and functioning, despite everyones efforts to help me. I see I have a backup of files on my PC which I believe are from my 465T.

Which files do I need to reload from my PC to the NUVI to get me functional?

Should I put these files directly on to the 465T or put them on a SD card ?

Which File has all the POI's which Garmin provides?

As always thank you all for your effort to resolve MY problem.

BTW: What the heck is a JCV file ?

Can you describe what exactly is "not up and functioning"? Can you reconfirm that in your Map Info page, that City Navigator is there and is checked?

Which files? I don't think we can answer this given what we know right now. It'd be useful for you to compare your backup to your nuvi and identify for us what files, if any, are missing on the nuvi. You may also want to check file sizes and see if there's a difference between identically-named files between your backup and your nuvi.

Files to nuvi or SD? Again, we can't really say right now. Many files must be in the nuvi and in the correct folder of the nuvi. In general, I'd restore files to the nuvi unless you previously installed a full map update to the SD card.

Garmin-provided POIs are built into the map file which I expect is a large file called gmapprom.img.

JCV: this file (Dxxxxxxxxx.jcv) is your Junction View file to show major interchanges and exit ramps as an image when you're running a route on your nuvi.

More to the point: In the various threads, you've mentioned a couple times I think that the nuvi starts running a route, then fails due to "no roads" or some such error. I've asked before but I don't remember you answering it--is your current map installed to the nuvi itself or to a SD card? I ask because your problem as I read it is very odd in that you say you can plan a route and start it, but it fails soon after starting. This leads me to wonder if some file like the large .img map file is corrupt or can't be read at some point or intermittently over time. A map installed to a SD card may be more likely to be corrupt due to a bad card, bad contacts on the SD card or socket, etc. I'm also back to wondering if your map update download was corrupt given that you said it was something like a 7-8 hour download over a Mifi card.

Right now when I go find a say walmart, it states no matches found... BTW: it says that for all my destinations.

I have nothing on a SD card..

I believe all the files are in the correct folder.

I don't have a JCV file anywhere.

I DO have a gmapprom.img file on the Nuvi.

At this point I will load an OLD file(s) just to get me functional, till I can get to a HIGH SPEED connection and download the latest version.

Again..thanks

While CraigW is giving you some excellent advice and troubleshooting procedures. Let me answer one point you asked. Your unit, either the 465T or 465LMT does not have or display Junction Views so there is no need to worry about a JCV file. If you have one, the chances are that it wouldn't display.

The Garmin provided POI are part of the map data which is updated everytime you download a new map.

Before restoring any files, do another backup of your unit to a new backup file with the file name stating what it is AND the date of the backup as part of the file name. The files must be restored to the same place they came from, in this instance it will be the unit itself.

The Garmin specs say the nuvi 465 does not offer Junction View, so it's correct that you see no jcv file. (You do have Lane Assist but I expect that feature is built into the map file.)

The most common reason folks get a "No matches found" error is due to the City Navigator map not being checked on the nuvi. If your nuvi shows City Navigator and it is checked, then the map file is either locked or corrupt--with the result that you will only see the very minimal BaseMap and be unable to route to any location and unable to find any built-in POI.

The first thing to recheck is whether City Navigator appears on your nuvi's Map Info page and that it's checked.

Regarding gmapprom.img, what is its file size and what version of City Navigator do you have? Do you also see a gmapprom.unl file and a gmapprom.gma file?

"The first thing to recheck is whether City Navigator appears on your nuvi's Map Info page and that it's checked."

A while back you said it wasn't checked and then you did. Please verify.

Hi....
- Regarding gmapprom.img=file size -289MB
- version of City Navigator=Garmin City Navigator North America NT 2013.10
- gmapprom.unl = yes
- gmapprom.gma = yes

Hope this helps...

Again Thank You..

Craig....The DL was interrupted.

So you might be spot on with"I'm also back to wondering if your map update download was corrupt given that you said it was something like a 7-8 hour download over a Mifi card."

So if I have a good copy on my PC, not sure what files I will need to reload?

Nothing on SD CARD..

Thanks..

HI..yes it is checked.... Thx for checking..

It certainly does help. You only have a fraction of the map. I wouldn't rely on the files you have on your PC to reinstall.
Best way to do it is find somebody with a high speed internet connection, sign into your account, then use the manage maps feature and re-download the map to your Nuvi. I recall reading you mentioning you don't have a fast internet connection.

Why is the map 2013.10, it should be 2013.30 if you downloaded recently?

Edit: Gave it some thought, perhaps you had 2013.10 on the unit and skipped 2013.20. When attempting to download 2013.30 during the process of updating and deleting the 2013.10 map something went wrong and didn't complete the deletion of the map and failed to install the new one (2013.30).

That's a bad map file. It should be over 700MB

WOW... Yowser, UGH !!!

Shazaam dead in the water...

Although good news, now we all can stop beating our heads against the wall..

BTW: Do have a large file 1.5GB, but it won't fit on 465T... I need to get to the store and buy a NEW SD card.

Yes you are right on it.. DL was slooooo so I stopped it...

Thanks

On my archive nuvi files, the 2013.10 file size for gmapprom.img is 1,706,688KB so your file is about 17% of the total map file.

If you have a backup from a previous working map (2012.40?), my suggestion is to be safe and just for the fun of it, make a computer backup of your current non-functional gmapprom files (.img, .gma, .unl, and if there, .sum).

Then copy your previous 3-4 gmapprom files from your backup from a past working map and place them back on your 465. I give it a good chance that you will be able to restore a functional previous map, hopefully 2012.40 or something close. If so, thank goodness for backups, huh?

Note that when you're ready to update to the current map again when you have a faster connection, your myGarmin/myDashboard (and probably Lifetime Updater, if you use that) will say you already have the current map installed. You'll need to go to the myMaps tab of myGarmin and there should be a button to reinstall your latest map.

Good luck.

Bummer. If after removing your corrupt 289MB gmapprom.img file there's still not enough room restore an older 1.5B map file, then you have a problem. It's not as simple as placing the map file on the SD card. It may be do-able by possibly calling it a Supplemental Map but there will be some effort and renaming of files to do this and someone will need to guide you through what needs to be done. Calling it a Supplemental Map might even confuse your next update.

The best option is to have a new 4 or 8GB SD card installed, then do a map install from a computer with a fast connection and get the current map.

Then in the future, remember not to try a map update with a slow internet connection

Do you, by any chance, have a functional City Navigator on your computer for use with Mapsource or BaseCamp? If so, we can probably get you to install that map from the computer to your nuvi.

Hello...
"Do you, by any chance, have a functional City Navigator on your computer for use with Mapsource or BaseCamp? If so, we can probably get you to install that map from the computer to your nuvi."

Yes I do have MAPSOURCE.. I can't find the files for the maps..

I found this in a TXT FILE "Add Remove Programs.Txt"

Garmin City Navigator North America NT 2009.11 Update

Garmin City Navigator North America NT 2013.10 Update

Thanks for your perseverance, but I will wait till I get to a High Speed connection and DL the latest.

If you have a laptop, I suggest 3 places you can go for a wideband connection.

1) Invest the cash for a cup of coffee and sit in a Starbucks on a weekday afternoon.
2) Invest the cash for a soft drink and sit in a McDonalds on an afternoon or evening.
3) Visit your local library.

Buy a case of beer and go see a friend that has high speed internet

Boxcar...

I like your style...

Thanks..

It looks like this is all wrapped up for now, except for two final thoughts:

-First, I'm surprised knowing what I know now, that a map update could fail in this way. If a map download is interrupted, I was surprised to hear that the update process would continue and create a corrupt map on a nuvi. The map update process is a 3-step event: first, the download (several 10s of minutes to several hours long depending on connection speed and server's activity); then the map prep which takes a few minutes; and finally, the transfer of the map to the nuvi (a few tens of minutes whose length depends on whether the nuvi uses USB 1.1 or 2). I would have expected that an interrupted download would not proceed to steps 2 and 3--and until step 3 starts, the old functional map on the nuvi hasn't been changed. Some part of my expectations seem to be wrong given your results.

-Second, for future folks posting questions: here at The Factory we work quite hard to see all issues reported by others get resolved. One thing that probably delayed the resolution of this issue is that the information and responses were distributed between three (I think) threads and only when combining info and past responses from the various threads was an answer found. Issues like this can probably be handled more quickly if the initial thread is where all information is shared and a subsequent threads should be avoided.

But all's well that ends well so I hope you get your nuvi working with a functional map very soon--and the latest map update soon thereafter.

Canuk... Dang a case... a 6pk will do my friend & I..

I think this post is digressing..

CraigW..I will fall on my sword for posting different posts. Secondly, I had a problem finding the correct verbiage to capture the problem(s) I was really having.

A lesson learned by me and hopefully it will help others..

Thank you all for your help.

HI ...I have a 4GB SD card installed. I put a backup copy of my map gmapprom.img(1.2gb) on the card.

I had also removed a GPX file, bad mistake. I do have some GPX files on my PC.

When I go to the POIs all I see is "SPELL and Transit" icons..

I believe I need to add some add'l files, but clueless as to which files.

Baby steps to fix this, till I get to a HIGH speed connection late next week and dl the new maps.

Thanks..

In addition to the map there is an unlock file needed. It should be in the same folder you retrieved the map fro, It's the file with the UNL extension.

Speaking of installing files to the SD card, the folder structure must be the same as the main unit. The best way to handle that if you don't have a lot of confidence in your abilities is to copy the main unit contents to the SD card. Then you can delete everything on the SD and copy over the map and unl file again.

On older nuvi's like your 465T, you need to rename the map files from gmapprom.* to gmapsupp.* when you copy them to the SD card. The SD card does not support the gmapprom map name.

Also, make sure you copy the files into the \garmin folder on the SD card. There should be 3 files (after copying and renaming): gmapsupp.img, gmapsupp.gma and gmapsupp.unl

OH my goodness... finally back up and functioning. THANK you Alanb..

My map is 2011 but that is OK till I get to a HIGH speed connection next week to DL latest ver. 2013.30NA

Solution:
1) Buy 4GB SD Card
2) Create Folder on SD card=Garmin
3) copy 3 files into dir/to SD card
- gmapprom.img, gmapprom.gma and gmapprom.unl
4) Rename files in step 3 to
-gmapsupp.img, gmapsupp.gma and gmapsupp.unl ... per instructions from "ALANB".. my new hero
5)dbl check that your Maps are checked in your GPS.

6) Sing "Hallelujah,Hallelujah"

I don't think I missed a step, but if I did it's only because I don't recall...

BTW... will backup my SD card to my PC...just in case.

Thanks for posting this (and I agree that alandb gives good advice).

And - glad to read that you are doing a backup.
