Nuvi 765T Part 2

[Loon]

First of all, I want to thanks Bahathir-san for leading me to here, the 765T family.
Glad to find so many family members here.

By the way, I'm having one issue here. I can't get the WebUpdater to find my device successfully.

But I'm able to find my GPS device in Mapsource, though with issue.

Does anyone has any idea? Please help me.

Thanks!

I suppose your PC has not installed with Garmin Driver on USB port. Therefore your WebUpdater & Mapsource not able to link up with your Nuvi.

Try to install the driver under this link below. (Taken from Garmin website).

Bro Loon, another thing you might like to try is to change the USB cable. I had this problem with one particular USB in my office which had been running fine on my old Nuvi 660 but had almost same problem with my new Nuvi 765. Change cable and problem went away. I am still scratching my head on why the old one does not work ...

Hi Bro Ed and Silver, thanks for the suggestions. I think I've figured out the root-cause, but unfortunately not the solution yet.
Please see the screenshot below:

Under normal condition, I should see "Garmin Device" under my Device Manager, then I would be able to update the grmnusb driver. But for my case, Windows automatically installed the USB Mass Storage driver for my nuvi and put it under the "Disk drives" and deprived me from updating the grmnusb driver. :(:(

I tried to stop the auto hardware installation under My Computer -> Hardware -> Driver Signing option but still Windows installed the USB mass storage driver automatically for it. Devastated.

First thing first.

1) Can your windows detect the Garmin drive ?
2) Can you browse files in the Garmin drive ?

What is your current firmware version ?

1) Can your windows detect the Garmin drive ?

Yes. No problem in transferring files.

2) Can you browse files in the Garmin drive ?

Yes. Same as #1.

What is your current firmware version ?

Software version is 3.10.

Thanks.

Ok what a relief, finally I found the solution!!

1] Garmin\GarminDevice.xml is proned to corruption.
(Edit it and scroll to the last line, if you see error message/code => Yes it is corrupted!)
2] Powering up Nuvi with SD card inserted will most likely corrupt the GarminDevice.xml.
(Maybe connecting the Nuvi to PC without turning it ON first will corrupt the GarminDevice.xml too but I have not verified this.)
3] If GarminDevice.xml corrupts, WebUpdater will not be able to FIND DEVICE successfully.

So the recommendations (for WebUpdater to find your device successfully) are:
1. Switch ON your Nuvi before connecting it to the PC.
2. REMOVE the SD card before you switch ON your Nuvi.

Thanks ALL!

Good to hear that . The current firmware/software version for EU/US region is v3.40.

If my nuvi's GarminDevice.xml corrupted, I will do this
1) Mount the garmin_drive.
2) remove garmin_drive:\Garmin\garmindevice.xml
3) eject the garmin_drive
4), Turn off and on, and the nuvi will create a new one.

AND there I was ALL the time doing EXACTLY the OPPOSITE ...!!!!!
... Maybe that's the reason why my 660 has been freezing up on me (requiring "hard" resets which wipe out all personal data ...)??

P.S. (.. off-topic story but somewhat related ...):
One "reliable" SGP Garmin distributor ...(in J.Sultan area) charged me $65/- to 'hard' reset my 660 - actually asked me to sit a distance away fm him while both of them 'wayang-wayang' pretending to upload/download and professionally diagnose my comatose Nuvi. (At that time, I did not think of hard reset and didn't really know how its done.) After our Garmin engineers miraculously brought Nuvi back fm the dead - TWICE, but they were generous enough not to insist on charging me again, I was seriously warned not to use certain maps (i.e. JW's & MFM's especially.. ) because these have been know to be "often virus-infected" ....!!!


I bought my 1st Nuvi fm them but needless to say after this valuable education in advanced GPSr maintenance that $65 is definately the last of my they will ever see .....

Tks for bandwidth ...

I had a similar problem with the WebUpdater. All I had to do was do a complete reset - by switching on the GPS with a finger on the bottom right corner of the GPS screen. After it booted up, you will be prompted to reset the GPS. Backup your data first!
