Hello Aekhong,
Is there any alternative way for me to use the Garmin ecoroute HD module without flashing US / EU firmware? Understand that the Thai fw doesn't include the necessary software to link up with the ecorouteHD.
You mentioned that I can go back to 3790V Thai if my hwid is still original. In the "About" page under "Device" it still shows as Nuvi 3790.
Thank you for your help
Chad
Additional note: I have an out of warranty 3770 T, should I flash 34xx fw on there instead? and restore my 3790V to the original FW if that is still possible?
