Re the license plate, in the UK we buy an sell them all the time. I have had this one for about 15 years.
People make them say things
K 1 NGS (KINGS)
S 1 NGS (SINGS)
P 1 LOT (PILOT)
COL 1 N (COLIN)
A 5 TON (ASTON)
Some people pay up to $200,000 for the most exclusive ones
The multifuction on the steering wheel is the one thing that will not work.
I have researched everywher I can think of but no one seems to do any interfaces for the MB CAN Bus.
I would pay a lot to get my multifuction working.
No - the prewired for phone does not matter as this system does not use it
The "PHONE" message appears in the instrustment cluster without doing anything else as soon as you either dial out or receive a call.
ONE OTHER thing you do on the wiring I forgot to mention is :-
You Plug the speaker Cable into the Black Box that was in the Radio and connect another cable from the Black Box to the radio in the speaker socket.
This allow the muting of the Radio when using the phone.
I put my Microphone up on the Roof Consol, but most anywhere in the center line of the Car will do.
