Hi all, I am new to this club as we have just bought our first Merc and we love it. The car came with Pre-wiring for the Becker map pilot but I am reluctant to buy the Becker unit and have to pay for yearly updates. I also have a perfectly good Garmin with lifetime free updates, but my preference would be to get my mobile with Google maps or Wayz maps to display on the Audio 20 unit. I have set up the Bluetooth for my mobile into the Audio 20 but can't seem to find a way to get the maps to show on the Audio system. Has anyone managed to Bluetooth Google maps, or connect another sat-nav to the Audio 20 system? Thanks in advance.
