Thank you all guys. I am very grateful to you. Finally I got in addition to all what I have: Media Player, Video player and voice command. I use the procedure provided by Catymag.
When I use the procedure of Lolypop000 I flashed as well and got an update.log file with the following
nüvi 34xx Series Software Version 7.50, UID: xxxxxxxxxx, HWID: xxxxxxxxx
------------------------------------------------------------------------------
Parsing "xrgn,140,1:/reg_140.bin"
Success
Parsing "reboot"
But no other features was added.
Once again thank you very much and I will be around to return the favor.
Sincerely,
