Are there any companies out there selling "Topo" maps that are compatable with the Nuvi 660 and maybe come on an SD card. It looks to me like the only units that will accept "Topo" maps are the hand held ones.
The only maps you can load are Garmin maps.
The nuvi 310, 350, and 670 are shown as being compatible with the Garmin TOPO 2008 maps with limitations. I can't imagine that there would be a reason that the 660 wouldn't accept them but I'm not 100 percent sure. I'm pretty sure some people here have loaded the TOPO maps on their 350's.
The nuvis themselves are not very compatible areas in which you would use the TOPO maps though.
As far as SD card vs DVD versions of the maps, the SD card can't be copied or used with your computer in any way. The maps only work with the GPS unit. The DVD version needs to be installed but can be used with MapSource on your computer.
When I 1st got my 660, I tried them. I'm actually quite pleased with the results, used them a fair amount. The only small issue is the base map is also displayed. As far as I'm concerned, that's not an issue, just makes the display a small bit cluttered. Worth it for me, as I can now see buoys offshore, mountain and all other elevations. I like them so much, recently ordered their newer Topo 2008. I can report back when it arrives if you would like. I've also loaded the old World map and am very pleased with that. Can see a lot of old roads... in Europe. May get the newer World map.
On the 660 you need to do something to turn on maps other than the preloaded map. In tools, Map, Map Info, check the boxes for the maps you want to see. Strange, but if you don't uncheck City Navigator, you get CN, even though US Topo is checked.
You can see what I mean by base map by unchecking CN from Tools, Map, Map Info.
comments after you get your new topo map and use it for awhile on your Nuvi 660.
I am interested in the Topo 2008 for my nuvi 200. I look forward to hearing what you think.
I got & installed the Garmin Topo 2008 package & installed it on my nuvi 660. I've combined 3 screen shots, same scale, they're in:
So far, I'm just a little disappointed. I've been using the old original Topo's on my StreetPilot III for years but can't do a screen shot. The SPIII got rid of the base map, just see topos. In my opinion, that's better. In case you're wondering, I did de-select all maps except 1 in my screen shots.
As you can see, City Nav had no contour lines, no elevations. Comparing topo 2008 to the old topo shows different detail in each package. I think I may keep both on the 660.
Thanks for the screen shots. Looks like your region is sinking into the sea.
When you drive with the topo installed, can you display an elevation profile?

Well the basemap resides in \Garmin\GMAPBMAP.IMG - so you could just rename it to something else to make it 'disappear'.
I suppose you could always put it on an SD card, in case you ever needed to recall it, while out in the field.
I think the limitations are that the Garmin topo maps aren't auto-routing.
So you have to put in via/waypoints for all the turns if you want to create a route.
Well no but it is not ideal. Do your routing on the NA map then switch to the Topo map. Don't go off the coarse or you'll have to switch back to NA and reroute then switch back to Topo.
Yep, that's what I do on my Zumo. I set the recalc mode to off so it doens't attempt to recalc also.
That's cool, didn't know that the zumo could do that, wish the 350 could.
I use the Garmin TOPO maps on my nuvi 680. You cannot route off the TOPO maps, but can plan 4-wheel drive trips and off road adventures.
I have a nuvi 750 and Garmin Topo 2008. I tried loading a test route from Topo to the nuvi. I have a GMAPBMAP.IMG file that appears in the Garmin folder. Can this file be deleted?
That is your BASEMAP!! Do NOT delete it.
Here are the map files that may appear on your unit.
gmapbmap.img - this is your basemap
gmapprom.img - this is your preloaded detail maps
gmapsupp.img - this is a supplemental map file
If you want to delete any supplemental maps you may have loaded, you can delete the SUPP file. But you don't really need to because it will get overridden the next time you load maps.
Did you you just sent a route or did you load a map, too? Also, I don't think that the US TOPO maps route.
Using MapSource and Topo 2008 I loaded a test route. I'm wondering how to permanently delete this route. Going from Tools to Routes, I can delete it from there. However, when I go from Tools to My Data to Import Route from File the test route is still there and can still be imported. So the file must still be in the nuvi memory.
I was quite positive the GMAPBMAP.IMG file was important and have not deleted it.
I found the test route file as an EasyGPS gpx file, named "temp" in the gpx file folder. It looks like it can be deleted from there.
You can map a route with Topo by placing way points along your route.
Thanks for the help!
Yeah, the temp.gpx file is where that data is stored. And as you found out, you can delete it safely. But don't be overly concerned about it taking up much space as these files are fairly small in size.
You are right. TOPO maps are not very detailed when it comes to nuvis. Still, do you have some other suggestion about the maps I can use to get a detailed view? --- Mary-Anne Davis, programare iasi affiliate.
Has anybody tried this with the new 7x5 series???
Here's a great source for maps. I downloaded and installed the Arizona Topo (Garmin-compatible 1:24k in detail) on a 1GB SD card and it works fine in both my eTrex and nuvi. Check to see if the areas you want can be found here:
The AZ topo is a free map, although the author does accept donations.
I tried to download Mapsource from gpsfiledepot, but it says that I have to have a previous version on my computer?
Before I can download and try to use the topos.
I successfully installed Topo 2008 on my nuvi 660. You have to turn off the city navigator first, then the detail from the topo maps will show up. I have had topo maps on my nuvi for almost a year now, and no problems. I haven't tried to map any routes yet though.
The US Topo maps are not routable. You will have to plot the route with your City Navigator maps active and the activate the Topo maps.
I will attept to upload Mapsource Topos to a Nuvi 255 tonight and I will post the results soon.
