Hi , any one here can post links for nuvi 660 firmwares in version 460 and 470 and 480 because i experience some problems with the bluetooth functions on the firmware 490 ( i ever had this problem on the past and i tryed much solutions like enter in maintenance mode to update bluetooth firmware, and other things but the only thing that solved for a long time my troubles was to revert the device with older firmware but don't remind if it was 460 , 470 or 480)

the trouble is that when i try to activate the bluetooth in the nuvi = the device freezes and does not whant to boot ; i need to put off the device and reboot him , but the bluetooth is still off and if try to activate again it freezes again........

so please if you can post links for 460 , 470 and 480 thanks a lot
