New Map 835.2419 Released

All your old custom POIs should still be in your old map's folder, if you can find that on a backup.

All you need to do is copy all the files with .ov2 and .bmp extensions from the old map's folder and put them in the new maps' folder on the TomTom.

You can do that with Windows Explorer - make sure you have it set to show you all the file extensions (in XP this is in the Tools menu / folder options / view tab - then UN-tick "hide extensions for known file types".

I’d like to thank everybody here, who’s posted solutions because after I’d upgraded to V835.2419 I too had to replace the mapsettings.cfg file with the previous one that I’d backed up before the upgrade and I also had to operate it from the TT Home Emulator before I could get the 730T to work.

I’ve been using the V835.2419 maps since installing them on 21st August 2009 but I’ve not had traffic working. So today I trawled through this thread to get the answers. As of 15:00 on 3rd September 2009 I now have traffic.

I’d like to especially thank AndyVaughan and mikealder for their advice on getting the RDS-TMC traffic to work with the following advice:

Manually extract the tmccodes.dat and traffic.dat files from your downloaded map and overwrite the files in the map folder on your TomTom unit.

Then delete the gnsdata file from the gns folder on the TomTom unit.

Edit: I just used the sound advice found on the PocketGPSWorld forum, i.e. this thread) and at no point did I follow any advice from TomTom which includes:

Backup (although it is good to backup regularly, via Windows Explorer)

Format

Use the Clear Flash tool

then re-install everything

Credit where it is due though Andy, it was you that first spotted the mess the v835 map update did to the Traffic related files, I have repeated this advice about the files being 0Kb on at least 5 other GPS related forums so the issue isn't just affecting a few users.

I wonder if TomTom are still offering pathetic advice on how to resolve this issue (Backup, format, clear flash then re-install everything) rather than e-mailing callers a copy of the post detailing how to fix the problem - Mike

Just a case of piecing it all together from the problems and resolutions already posted really - I think you spotted one of the traffic files being 0Kb before I did - I just took the approach that if one file is 0Kb and others seem to have been screwed up as well then replace all of the traffic related files.

The gnsdata file is an old fix for a multitude of problems - file access errors, traffic not working etc - the rest of the advice was just good practice of installing maps manually.

Wasn't up to the same quality of your post on how to roll back Navcores manually, I didn't have time (or a x20 to hand Laughing Out Loud

) to post screenshots.

Notice how us XL LIVE users don't seem to be suffering from the same problems?

I've just been sent a customer satisfaction survey by TomTom - not the usual post-support call one, a much longer and in-depth one about my experiences with TomTom in general and my 740 Live in particular. Very unfortunate timing on TT's part. Twisted Evil

See my other thread re traffic no longer working. I have done everything from this forum, and everything from TT, and still no traffic.

Oh and no gnsdata file in the gns folder either. Crying or Very sad

Did you look to see if your traffic.dat and tmccodes.dat files showed 0 bytes on the unit?

(if so, extract the same files from the compressed map cab file and use Explorer to copy them to the route of the unit).

They are fine, 6.3Mb for the big one, and 1kB or something for the little one. Can't tell you for sure, its back in the box, about to be drop kicked over the garden wall Laughing

Having driven to Birmingham airport this morning, from Milton Keynes at 7:30, and then to Heathrow late this afternoon, 300 miles all told, traffic would have been good, but no, its not available any more Mad

Try and do a full Windows Explorer back up of your device.

Does it succeed? or do you get an error that it can't access a file?

Worth running a Windows Checkdisk with Automatically fix file system errors selected. If you get a hidden folder called FOUND.000 or similar then you had some corrupt files - time to get an old backup on the device after a full format as FAT32.

A hard reset and a clearflash or two might help as well.
