My 760 is still running FW v3.4, and I have no real issue with it. I need to update the map (still running 2008 map) and at the same time would like to update the voices too.
Now I've read all the horror stories here about updating the FW resulting in stuttering. How can I update map and voices without updating firmware?
I read a while back that if the file GUPDATE is deleted before rebooting, that would prevent FW from updating. I tried to search for the thread but can't find it. Any help would be appreciated.
I got my Nuvi 755T yesterday and in the night I updated it to new 2009 maps everything went fine; ofcourse it took me 3 hrs to finish the job. 2hrd to download and 1 hr to install.
Just make sure that you do not disconnect or lose connection between your PC and GPS during the update and you will be fine.
My 760 has the 4.60 firmware and the updated 2009.11 maps and I'm using the new Jack 1.70 TTS Voice and I have no stuttering or any other problems.
To actually answer your question, I believe that deleting the GUPDATE.GCD file will do exactly what you want.
Or you can download the voices individually. Read the page source for instructions.
I downloaded the map update with firmware v4.2 on the unit without having it update to v4.6 by doing the following:
In the Garmin folder on the unit is a file called "GarminDevice.xml". I opened that file in Notepad, on the second line is:
I changed that to:
and saved it back to the unit (after making a backup). When I went to the registration process it didn't force me to update the firmware and allowed me to d/l the map update.
- the "GarminDevice.xml" file is recreated every time the unit boots - so you _have_ to make this change after the unit is plugged in and just before you do the update. If you reboot the unit after the change and before the update then the change is lost.
- This worked for me. I'm not guaranteeing it will work for you, and once the v4.x upgrade is done you can't go back to v3.x without losing Bluetooth permanently, and maybe other problems.
- Given the risk it's probably a good idea to delete the "gupdate.gcd" file after the download regardless of whether it seems to have done a firmware update or not. There's a good thread on this at GPSPassion:
Were I you, I'd update to V4.20. I've had no issues with it. You can get it here: http://gpsinformation.org/perry/nuvi/.
Yes, if you delete GUPDATE from you nuvi immiediately after the Garmin update, but before disconnecting from usb cable, it will not update to the most cuttent version on the next reboot.
I would use this link as it is direct from garmin.
Thanks to all the suggestions. I used gpsaccount's method and was able to update the voices without updating the firmware. Now to see if it works on the road.
Seems to me the latest update fixed the stuttering problem at least on my Nuvi 760
