Hi there, i have a 2003 RR vogue with the car phone prep including under armrest cradle. I have bought a siemens OEM phone and tried syncing it last night!! turns out out all i managed to do was revert back to default german language!!!

it would be great if anyone has a guide on how to set this up?? Also on a minor note the little 0/1 switch in the cradle base
how do we know which way is 0 or 1 seems logical but i am convinced it may be opposite to my thinking?

Any help would be greatly appreciated
