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

Have you activated traffic subscriptions? The traffic receiver must be connected to the nuvi in your car ,fix satellites and nuvi will give the code to activate it in MyGarmin page.

I am living in Singapore...
Don't think the traffic info needs a subscription....
From what i see in the developer info page.. the GTM25/GTM35 is not even detected.... anyone having similar issue?

OK, here is the deal after almost 2 weeks of testing.

Everything was working fine, apart from a couple of drops of EcoRouteHD device during driving, however, today, after we have arrived at destination, I took it out of the cradle and when I pugged in back in, I have lost all "options" inclusive of bluetooth, and device has "abnormal shutdown", did not show the map, although it was showing the road I have been driving at. After hard reset, same again, however, this time it has been showing the map on the screen. Also, what I have noted previously to this was when I have been driving without navigation, just showing where I'm going, the "car" had been "jumping" similar to what some other people here have been reporting in when used in test "NonSat" mode.

Once I got home, I have copied all XML files with features, rebooted, cleared all data, and rebooted again. Paired it again with phone and ECORouteHD. Seems fine now....

Never mind i will try and reflash the firmware again tonight... could be a bad flash....
Report back again....

Ok.... must be something wrong with the unit....Traffic adapter do not work even after flashing back to 3760 firmware....
sigh... lemon set....

Found the issue... should be a fault cradle... I mount the gps onto the cradle no sound is coming out from the speaker behind....
Sigh... time to get another cradle....

Mine had the adapter's pin stuck all the way inside the adapter once and the all the system was out of power.

Hi... yeap there was power... in fact the unit shows charging.... but it can never detect the traffic adapter properly....
I guess just bad luck that cradle can also get spoilt.....

Before you buy another cradle make sure that it's not the 37xx unit or the power adapter.
The FM radio receiver is inside the power adapter cable.
Sometimes the cradle interface pins on the 37xx unit can be faulty.
Maybe you have a friend with a 37xx and can do process of elimination.
