So many months ago, I did MK3 SYNC3 Upgrade and installed the 8" Screen with NAV. Thats all working fine,

Next I upgraded the IPC and that was fine, everything worked perfectly, including rear sensors etc,

Today I upgraded the firmware to MK3.5 software so I can have digital speedo. Thats all fine and working but now lost reverse parking sensors beeps.

Installed a MK3.5 PAM and updated the firmware. Checked central config and parking assist is on but no reverse beeps.

What am I missing

    You need to update your parking sensors to mk3.5 physically for the beeping to work is what i've heard

    Forgot about this thread. So the fix is to update BCM firmware. This fixed it but warning do at own risk as it can mess up immobiliser. 

    Everything is fully working with no issues. 

    Might change my mk3 steering wheel for mk3.5 at some point.

    Hi,

    Does this change the configuration to CGEA instead of C1MCA ?

    Thanks
