Becker Map Pilot - Sat Nav for Mercedes Benz
This has just come out of my SLK which has been returned at the end of a PCP plan.
It will fit all models fitted with the pre fit that sits in the glove box - it just slides in.
It is in full working order and has both UK & Europe maps.
This is the best Sat Nav I have ever used and always got me to my exact destination, without fail.
