I just updated my Z1 to Z3 with a new drive. Here are the versions I get:

Version 05.0000

CDDB 10-01-0010

Platform 3.000200

GPS Program Version 1.200000

HDD Application Version 5.000000

Am I set with the above versions for the "2 wire" bypass or do I need to upgrade any of the above? Once the car starts moving it kicks me out of all unlocked features. I read through some of the posts and it said it is probably the bottom right yellow wire is not grounded, but I want to know if I need a firmware update first before I start tearing the radio out.

Thanks

Your firmware is fine and fully supports the 2 wire bypass. correct your wires, press the reset button and you should be good to go.
