Thread: Nav for harman kardon audio 20

Hi all
Recently bought myself a W204 C200 CDI MY11 (Upgraded Model) with vision package which includes Haron karon Audio 20 system. After looking through the MB accessories catalogue I realised that I can buy a Becker Map Pilot plug and play nav system. However after enquiring at my local stealership, the system is not available in Australia.
Can anyone out there please recommend me an alternative plug and play system?
I've tried other Forums and no one can help me out.

This is a 3 shell trick. You order it for W212 and then install it in the W204.
