670 map update help please

[malcolmbunn]

I have a 670. Purchased lifetime update of maps from Garmin. Loaded my European update map, no problems, then loaded the American update - mistake!

According to the device the only map installed is the CN North America NT 2010.1 and certainly no detailed map is displayed for Europe.

According to MapSource the only maps installed on my PC are City Navigator Europe 2008 and City Navigator Europe NT 2010.1. I've tried using the upgrade software provided by Garmin, but it reports "an upgrade path was not found for your currently loaded map" which probably suggests the old (2008) map was wiped.

Would appreciate suggestions on how to get my Europe map back onto the device.

Thanks in advance

Presumably, both update procedures assumed that their map should be called GMAPPROM.IMG and one overwrote the other

But since your Mapsource installation thinks it has a copy of the European map installed (I assume it's unlocked?) - you could use it to build & transfer a copy back to the Nüvi. You'll have to manually select all the regions you want and you'll end up with a supplementary map (ie in GMAPSUPP.IMG). You can then (probably) rename it to its 'proper' filename of GMAPPROM1.IMG. (Actually, I'm not sure which map should have which file name, or indeed, if it makes the slightest difference).

As I pressed the 'submit' button last night it occurred to me that I could use Mapsource to reload my europe 2008 map, then use the unlocked upgrade.

I used mapsource and loaded the 2008 europe map then spent hours trying to get my 670 to start. It states, 'loading maps', a green line appears across the screen and as a second one went across the screen, it would shut down!

Have at last got it talking to my PC, but Map Update still states that 'an upgrade path was not found'.

Now cannot get my 670 to boot as it 'crashes' as it loads maps. Can I send it back to Garmin for them to rectify?

Is there a way to 'reset' the machine?

Will try the .img file if i can get the 670 to boot.

thanks for help
