Question about Garmin StreetPilot c340 GPS Receiver

1 Answer

Lost Memory and Map Data

MyGarmin GPS c340 worked perfectly well until the following:
After using WebUpdater to download 5.9 update and attempting to download the City navigator NT 2009 (failed), I lost all of my map data.
There are no maps on the GPS although everything else functions.
My questions are as follows:
1) How can I recover both the memory and my map data.
2) If the above requires a repair, is it worth it or should I scrap the unit and get a newer one.
Any assistance you can offer, will be most appreciated.

    Help! I also attempted to download an update to my Street Pilot 340 and lost all my map data. It gives my a picture of the US map with it pointing to Kansas - and I'm about a thousand miles from there. Has anyone been able to resolve such an issue? It just seems to be frozen. Very frustrating.

I just spoke with Garmin and they walked me through correcting the problem - very helpful. It is a matter of resetting the unit. Turn unit off, then press a finger tightly against the bottom right hand corner of screen, holding it while turning unit on. When screen comes up, let go of power button but still pressing bottom right hand corner of screen, answer question regarding deleting defaults. It is tricky and may have to be done a couple times. Then you will answer questions regarding time zones, etc. When finished with this, turn unit off and go outside in order for the unit to re-aquire satellites. When all four bars on upper right hand corner turn green, you're back in business - or at least it worked for me. Hopefully this will help, but you may want to call Garmin as they are really helpful and can explain it better than I can. Good luck!

How to update my garmine nuvi

To update the maps you need first to register it. Connect it to your computer and go to Select your country and then click on myGarmin. Then click on Register your Garmn Product. Follow the prompts. You'll be asked to create a username and password. Write them down and remember them as you'll need them anytime you update your maps.
After you've registered go into myGarmin and click on myMaps. Your maps will be shown and if there's an update it will show Update Available. Click on this and it'll bring you to the download site. You'll have the option to download if you have broadband or to buy by dvd if you don't. You'll need a credit card to pay.

To update your software: If you're updating the map it will normally first update your software but if you only want to update the software and not the map connect your satnav to your computer and download webupdater from and install it. When it's installed it'll look for updates to your software. Follow the prompts.

I tried to update my garmin. The screen doesnt move (or continue to download) I allowed for block ups.

You need to download and install the Garmin WebUpdater and Garmin Communicator Plugin both available from Garmin's website onto your computer. This allows updates to be installed directly to the 765T and provides the necessay USB drivers as well. The 765T must be connected to your computer when performing all updates or upgrades.

You may need to create a MyGarmin account and register your Nuvi 765T.

Resetting the 765T: with the unit off, press your thumb or finger in the lower right corner of the screen while turning the 765T on. This will clear all user data, base map software will remain intact. Connect 765T to computer and proceed with the Garmin WebUpdater.
