Hi Marius B,

Thank you for your detailed steps, with pics too. Now I really want to go home and test it out! Does it decrypt the scan codes and error codes on the Nuvi too?

Unfortunately, on the Thai / Asian fw, I did not get the 3 bars under the ecoroute menu. Which was why I had to flash my 3790V with 34xx US fw. It should work now (have not had the chance to try it yet) but the ecoroute menu now under the 34xx fw requires the ecorouteHD hardware. So thats a good sign. Will report back to see if that works, as this was the main reason I took the risk of flashing the US 34xx fw in my brand-new 3790V unit, although I do have an out of warranty 3770T.

I really appreciate the time you took to show the screens step by step.

Hi,

Yes, it will also decrypt the error codes.
The application is also under the ecoRoute Tab.

I hope you will make it work.

Regards,
Marius
