nishant880,

I read somewhere that the firmware update is suppoded to fix/enable the use a hands-free car kit which is avaiable from Handspring. Now as far as I know, the "patched" firmware upgrade was designed to remove the lock specifically, but may in fact also fix issues with the car kit. I can niether confirm nor deny this as I have a soft-top on the Jeep and it's way too noisy to use anything but a headset.

Cheers
