Garmin Nuvi 610T lost maps

I bought a Garmin Nuvi 610T today.

Got it home, put some charge in the batteries.

I had a quick play, putting in some locations.

I then ran the software updater and registration.

I have not lost my Mapsource maps, just got the basic trunk routes showing. I tried reset but there are no maps loaded - Map Info button is greyed out.

Anyone any ideas?

Did you take a backup before you performed the update?

I suspect, however, the maps are now gone, and you'll need to return the unit for fixing.

I thought these problems were solved with the latest WebUpdater - unless you were running an earlier version of WebUpdater...

The maps cannot be downloaded (way too big, and there would be copyright issues), so without a backup, it's back to Garmin / supplier I'm afraid.

Unfortunately no!

I spoke to Garmijn Support this morning and they confirmed that there was a faulty batch and it would have to go back.

I have taken back and got a refund (no others in stock locally). I liked the unit so will pick up another at the weekend when I will be going near some large shops.

Is there any way of identifying whether they have the same problem and liable to lose the maps if I do a software update?

Is there a way of backing up the maps before doing an update so that they can be recovered if the same thing happens again?

I doubt you will be able to tell a good or bad unit from stock, although it may be worth waiting a couple of weeks and then buying from someone who turns over a lot of stock, thereby hopefully you will get the fixed stock.

Yes, search these forums - by connecting the unit to your PC, you can see the files on the unit, you just need to *copy* (not move) all the files on the unit onto your PC.

Thanks, if I was not going away then I would waited until they restocked as that might have been fresh stock. I should be able to get a larger shop which as you say will have a quicker turnover.

Yes I could see the files using Windows Explorer but that was only after I had lost the maps. I will just backup everything.

I have got a replacement Nuvi 610T today.

Software version is 2.10 - is this liable to crash when I update or is it dependent on the unit ID.

Also it does not seem to recognising the GTM12 - the screen asks me to connect the traffic receiver to the nuvi to use Auto Tune but I have connected it!

About shows
GTM S/W version N/A

That's a very old software version, which I believe did suffer from a "missing traffic receiver" bug. I've no idea what caused your original unit to fail, although there are a few things you can do to minimise the risk of problems...

1. Take a backup of every file and directory. If you have a problem with the the \garmin\gpx directory, it may be corrupt. If so, backup every other directory individually, and then backup the current.gpx file from that corrupt directory. Before progressing, run a "Scan for errors" CHKDSK within Windows and clear up the corruption.

2. Do not use WebUpdater. Go to the www.garmin.com website, find the 610, and download the latest firmware for it. Run this to upgrade the firmware.

3. If you have the missing maps again, we can go through re-installing the few missing / corrupt files, but this will only work if you have backed up every single file in step 1.

Finally, that is a hell of a software version jump - was the other unit on the same earlier firmware? If so, it might be a problem that you need to run through an intermediate firmware for some reason.

Oh, and I suspect you mean GTM21, not GTM12 for a 610T.

Where did you purchase it from? Garmin's traffic information webpage shows that the 6xx range is only compatible with the GTM21 (which is a combined power cable / FM traffic receiver) as opposed to the GTM12, which is completely separate from the power cable. Garmin's 610T webpage explicitly states the 610T comes with a GTM21.

Even moreso, the 610T package from Garmin is a 610 with a GTM21 - anything else, and I'm not sure quite what you have bought. It's possible it's not a true Garmin dealer who has sold you a bundle cheaper. Having said that, I could be wrong, and it's exactly what one should expect from Garmin.

If the unit won't talk to your PC, which worked fine with the last unit, I would send it straight back to the retailer and get another one.

Personally, I would send it back, based on the not working with the PC, and try another one.

Probably end up doing that but on the road early tomorrow and won't be near anywhere convenient until later in the day so will speak to Garmin first.

Swapped the unit yet again today.

This one has a GTM21

As delivered the software versions were
Unit 2.60 3.80
Audio 3.20 2.30
GTM 3.70 4.10
GPS 2.80 2.90
Bluetooth 2.40 2.80

Second figure is after updating and maps not lost this time!

Not got the GTM working yet but will try again tomorrow with newer software and see if it find anything.

You may find the GTM21 takes a few days to settle down and provide traffic. You may also find you are in part of the country without good TMC signal (or even an area of the country with no signal at all), so be patient, and try it in different locations.
