F10 NBT & RearViewCamera 3AG retrofit

[BubbleB]

Remove 3AG and add 5DL. Then make a tal calculation and flash the TRSVC. If you have flashed change back to 3AG and code the module.

Thanks for the information. 

Remove 3AG and add 5DL: VO ==> I am capable 
At the end, remove 5DL and add 3AG: VO ==> I am capable 

Make the TAL calculation and flash the TRSVC...could you just elaborate a bit?
Thanks!!
