1390T Keyboard Delays/Freezes When Entering Text

I have a 765T (this is actually a replacement 7655T that Garmin sent me when I sent my other unit back in for repair due to a problem with the screen - pressing the screen and something else on the screen being selected.)

This replacement unit didn't seem to suffer from the same problem so I figured I was fine. However, I've been noticing that this replacemtnt unit tends to hesitate/freeze when entering text sometimes. I notice it mostly on the Where to go> Points of Interest area. If I select "Spell Name" or "Spell" after selecting any other options in this area, when the keyboard comes up and I start typing, when I get to the 2nd letter, the screen freezes for about 3-4 seconds. It looks like the unit registers the letters if I keep typing and they just all show up at once after the screen unfreezes. The unit doesn't behave like that in any other areas where you have to use the keyboard but only inside "Points Of Interest" areas. This is very annoying and I am pretty sure my original unit didn't behave this way. Anyone know how to fix this?

I have this same problem as this when I updated the firmware on my 1390T to version 6.20. Does anyone know how I can re-install an old version of the firmware/software back. I didn't have this problem until the update.

Reset

Note: I tried a hard reset, recalibrated the screen and re-installed the firmware v.6.20 and it didn't make any difference.

Hate to say, but changing

Hate to say, but changing firmware won't help. The problem here is that the CPU is overloaded by the demands of the firmware and thus typing suffers as a result. My 1300 also has this problem. Later units, especially the 2013 line, use much faster processors with more application memory and should not have this problem.

Worked Before

But, it worked perfectly fine before. I have the 2014.20 map, a full 779MB JCV and a Speed Camera POI installed on a Kingston Class 10 8GB microSD card. Before when it was running normal, I was running the first free upgrade map on internal memory and original firmware that came with the unit. Could having the map on microSD have something to do with the freezing/delayed key entry on the POI Spell Name screen?

Anecdotal thoughts

The Barnes & Noble Nook Color is a 7" tablet/ereader often tinkered with so that the android OS can run the device from SD card. A large number of people have done this and reported their results. What's sort of odd is that the most reliable SD card to prevent crashes, reboots, slow downs, etc. is the Sandisk brand Class 4 SD card.

Given the cheapness of 8 GB cards these days, if this were my slow 1390T with the map on a SD card, I'd try a Sandisk card. Amazon, Wal-Mart and RadioShack should always have these in stock. I would avoid eBay, especially from Asian Sellers for SD cards.

I offer no guarantees on results but it would be an experiment I'd try--and I would post my results here for the benefit of others.

One last thought regarding speed classes. Here and elsewhere there's no uniform consensus regarding the benefit of using faster cards in a nuvi. Some report faster cards result in a faster nuvi response while others report that Class specs are for writing to the SD card while using a map on SD reads from the card and therefore speed isn't important.

I know you were addressing

I know you were addressing the OP, but I am running a Sandisk Class 4 card, a 16GB version. After doing a quick test on my 1300, I believe the lag is caused by the nüvi processor having to read the data from the MicroSD. The very act of reading taxes the CPU and slows the entire device down. Remove the card from the device and the lag apparently goes away.

I'm in agreement with you that the processor is not reading fast enough thus causing the lag.
But if member jackrabbit000 removes the SD card he is also removing the ability to search points of interest. He states the map and JCV file are loaded on the SD card, he will then only have the Basemap when he reboots.

I myself only use Sandisk cards as CraigW mentioned, I've owned many and never had a problem with any of them. I agree with CraigW, a good choice for his 1390T would be a Sandisk 8GB class4 card.

He further stated when the maps were loaded on the Nuvi it worked properly so we can assume reading the SD card is causing the lag. A solution to this would be to remove some files from the Nuvi to make room, then use MapInstaller to create a smaller area of the map. He can have the full view Junction View remain on the SD card.

Obvious?

I figured it would be kind of obvious that were the card removed the ability to use its maps would also be removed. Thus why I didn't mention it.

Will Experiment

Thanks guys for all your input. I'll pick up a Sandisk 8GB Class 4 card today and try it to see if it makes any difference. I'm also going to try an remove some files to make room for a smaller map and see if it will make a difference without the microSD card and report back. Strephon might be right that the CPU is taxed trying to read the POI's from the card. Especially when it worked fine before with the older map installed on internal memory. I called Garmin this morning and they said that they have not heard of this problem with firmware 6.20 but will escalate it and hopefully the engineers will look at it and make another update. As mentioned, I can't remove the card because all I get is an error message "No Map Data Available". But what I can't understand is that my wife has the 265WT and the same map is on her SD card and the keyboard entry is fine and it's an older unit.

Thanks

Thanks for the update. I love it when folks are willing to experiment...

Re: removing some nuvi files. I hadn't expected this, but with my nuvi 855 (a notorious model for auto-reboots and freezes) I found that after removing lots of unneeded files (foreign language, help, voice, text, etc.) to free up more space, that my 855 seemed to respond to entered typing faster and it had fewer freezes and random auto-reboots.

How Much Free Space Available

I remember reading some threads that said Nuvi's need a certain amount of available space to peform efficiently. I can't remember the percentage nor as hard as I search can I find where I read it.

@jackrabbit000
How much does your Nuvi display as available space?

Right now I have 1.21GB of free space. I just bought a Sandisk 8GB Class 4 card and will be trying a few things tonight including trying to free up some space and loading a smaller map into the internal memory to see what happens.

I'm just wondering

A SanDisk Extreme Pro SDHC UHS-1 Memory Card states that it can read speeds up to 95MB/S.

Would this type of card make a difference ?

Well It Didn't Work

I tried all of these and nothing worked and didn't even noticed any change in freezing or delay at all.

1. I tried the Sandisk 8GB Class 4 card with the 2014.20 map, full JCV and the speed camera POI.

2. Deleted all un-necessary file from the GPS and got 1.66 GB of free space. Using the above microSD and the original Kingston card, I Rebooted the unit and did a reset.

3. Removed the JCV and POI from the Sandisk microSD card and Kingston.

4. Installed the East Region map only to internal memory using MapUpdater tried with and without small JCV

5. Reinstalled the 6.20 firmware and reset, tried both cards.

6. Shutoff any unnecessary stuff like Bluetooth, ecoRoute, re-calibrated the screen.

7. Back to full map on microSD card. Every other screen that requires keyboard entries is really responsive except for the Points of Interest> Spell Name.

Sluggsh performance.

Also try clearing your trip log frequently. On boot-up the Nuvi has to load in the trip log. Clearing the trip log can improve performance and free up memory.

Try connecting a Nuvi with a large trip log to the PC and watch the green progress bar before it finally shows the PC to Nuvi link icon. This can take up to a minute on a Nuvi with a large trip log.

Clear the log and connect the Nuvi again the the PC. The link will be established in less than 10 seconds.

I already deleted the trip log quite a few times already and yes, it does connect fast to the PC. I'm pretty sure that it's a firmware problem.

Firmware?

Looks like you did a thorough job in trying all troubleshooting possibilities. Free space is not an issue.

If you still feel you’d like to revert back to an older firmware, you can get older versions from the link below. Please make sure you have a complete backup of your Nuvi before attempting a firmware backup.
There are 6 links to choose from, several are duplicates, just click on one and it will be ready for download with the version number since it doesn’t appear at the link.

Scroll down to the nuvi13xxand14xxserie..> 04-Oct-2012 11:40 16M
This is version 610.

590 is also available at:
nuvi13xxand14xxserie..> 04-Oct-2012 10:26 16M

This is what V 610 file will look like:
Nuvi13XXand14XXseries_GCDFile-MTK_610.gcd

Now here lies my problem, I've used the site for other old firmware updates but they were .exe files.
The backup firmware on my Nuvi is named "GUPDATE.GCD".

I'm not sure if you have to rename the downloaded file to GUPDATE.GCD and over write the existing one to get it to work. Hopefully members more knowledgeable than I can advise what to do with the file.

One last thought is that you have a corrupted map file. I’m not sure this is possible but maybe the map is fragmented and causing the Nuvi processor to work harder and can’t find the POI location fast enough causing the lag when typing.
It’s a long shot but may be something to consider.

I already reloaded the map 3x already. So I don't think it's the map itself. There is no link, can you post it for me. I did a search on Google, every link I click on sends me to software v.6.20.

Sorry

My apologies, I should have noticed the link was missing. Here it is.
