I wanted to flash asian firmware for 3D , calendar and media player.
You are right , following the instructions in the provided link , I managed to flash to 34xx without any problem so far. Right now playing around.
In the instruction I don't unsderstand the following:
To get all the available features you must copy these *.xml files in attachment in /Garmin
(example /Garmin/DeviceConfig_MP3_Enabled.xml)
NOTE on 1-8-2012: We realized that ,since sw 7.10 ,cant enable or disable features anymore.
To do it , must go back to older firmwares-

Which *.xml files? and where to get them?
Once again thank you.
