Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

I'm using the original GTM supplied with my 3760T, a GTM35.

I'm not able to check with a different cable.

Here are the screenshots:

Reception seamed to be a bit poor today, so no payed traffic providers...

The screens are ok, subscription and tune, despite the weak signal. It may be an occasional problem, lack of traffic information in the RDS signal, intermittent failure tuner (happens a lot in GTM25and 35 cables) or some unexpected blockage in the firmware update. For this last situation, just go back to the previous firmware and check if it works and then reinstall the 34xx fw and check, it should work. For failure tuner you should observe the screens Traffic tuning, moving the cable in various positions and see the result, if nothing happens the problem is not out there. To know if it is some intermittent problem with the FM radio that transmits the signal, the ideal would be to check if other garmin gps has worked correctly. It is also important to test gps and cable separately with different devices.

Hello, how do you know that it is based on 3490? How did you arrive at it's conclusion?

What happened in the original version?

Check this link is the version for your model.

how do i know, what i have?

Unless it's a coincidence, 'normal' 3490 latest firmware is also V8.20, so if it's running the same fw and is hardware identical there won't be a lot you can change. Earlier model BMW branded Garmins did have some differences in the cradle for instance. If you're only wanting to change the Start Up Logo, that's no problem but first ensure your unit's HWID is 1376 before using the pack in Post #1.

PS: I've removed the Unit's Identification Number from your image to protect you.

This thread is for nuvi 37xx conversion to 34xx.
If you already have a 34xx probably you don't need to convert it.
Look at Garmindevice.xml in Garmin folder to discover which files are supported by your nuvi and check what do you have in .System\Diag\html
