Or am I going to be the first one on TYF?
Supposedly on 07-08 vehicles, you swap the VCIM and you lose On* but you gain Bluetooth ability.
On 09+ vehicles without Bluetooth, you put the VCIM in and you can keep On* and Bluetooth too.
VCIM is like $200 and takes about 15 minutes to install.
I'll use this thread as a reference since that's where I found it:
