Posted: Fri Feb 22, 2008 2:39 am Post subject: Can't unlock map's 770 |
|
|
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.

Garmin wouldn't knowingly put out a firmware update that doesn't work. No one would knowingly do such a thing. Why would they?
Perhaps your units come from a faulty batch where the update doesn't work. Perhaps you have a corrupt firmware download. Perhaps there is a fault with 770 in general but we've not seen any other reports of this, as far as i am aware. |

That's all well and good with something as simple as the i3, but with more complex Garmins, that have, say separate GPS firmware, bluetooth firmware, TMC unit firmware, the only way is to use webupdater.
The updates for these things don't seem to be released for general download and manual installation. And I suspect webupdater expects a fully up-to-date unit, before it'll let you search for additional software. |

Well I've no issue in you "tidying" threads, but you could have left Phil Hornby's post in - that was quite informative and useful. |

So for mass-storage addressable units (ie everything from C5xx onwards), a window of opportunity exists, where you can have a poke around the file system (BEFORE you reboot it), and simply delete anything you don't like the look of (*.gcd, *.bin).
Also, you can edit the inventory file (GarminDevice.xml), to lie about the current state of the unit's firmware. (It's regenerated at every boot, so you're only making a temporary change). I've been doing this for a while with my C510 - because I absolutely don't want the main firmware updating past V5.4.
Webupdater has surely got to be the best way of finding new software for your unit... |
