I have just had my second 770 today and i installed the garmin webupdater, when it found the unit it sead that there was a update from 2.20 to 2.60. so i folowed the info it did the updat moved out side to get a signel then when it has finished it say's can't unlock map's

this being my second 770 as the first one did this to plus when i did get the maps to load after making the gmapprom.unl file it wold do a cold boot tap here then here and so on every time it was switched on Plus NO bluetoth i asked the shop that i had it from to have a look at it and thay sead it was not working right and that thay had receved lots of problems with the 770 that have been up dated.

this time i backed up the unit just in case well it's not working at all even bluetoth has gone.

so this unit has cost me £21.00 in postage to date pluse £269.00 and will do nothing.

gues i will go back to my HP 4700 with TOMTOM 3 at least it works.

so here is my advice DONT upgrade the 770 from 2.20 to 2.60 better still dont bother with them at all try a tomtom.
why put a updat on there loader thay know is not working right? just to get every 1 to sending the units back to them for fun?

Personally I've never let Web-Updater install any updates. I usually download them and then install them manually.

You mentioned a backup. Can you access the nuvi internal memory and copy the files back?

I know that at least 2 people here have upgraded to 2.60 on a 710 and a 760 and all worked OK.
