I have a 2003 SL55 AMG with a Nokia cradle - I have no idea what Nokia phone fits it - the code on the current cradle is 230 820 06 51. A google search gives me no indication of what phone is compatible. I bought the Mercedes HFP phone cradle
I don't understand how the parts guy sold you this MB HFP device when it is obvious that it does not fit to a 2003 car (it needs UHI at the car).
Check from the manufacturer or ask here Electronics - MBClub Forums
if ViseeO would be compatible with your car. It looks like you have the 852/854 phone kit while on a W211 it should be 380, on the other hand 380 does not appear to be an option for the SL.
Your info has lead me to the right product... theViseeO MBU1000 Bluetooth for Mercedes Benz is the solution.
Thanks for your help chaps, hope it bloody works
With this the cops may leave me alone.... all I need to do is remember to wear my seatbeat and drive at the speed limit... PPppff!

All the rest should be straightforward but with an SL55 you should try to remember that the signs at the road are not indicating the minimum recommended speed.
