Universal Media Interface or Nav + 42
"Nav + 4 is a multifunctional navigation system and entertainment center available as a standard audio system upgrade for most MY08 - MY09 C-Class and MY10 GLK-Class vehicles with an Audio 20 CD headunit. Together, Nav + 4's map navigation, with real-time traffic for life at no additional cost, and in-vehicle music integration allows you to keep your finger on your music streams and your commute routes - all accessed simply and conveniently through integrated steering wheel controls or the central controller."
Dose this mean that we will get a free upgrade with real-time traffic? Multi-Media included?

Perhaps Vic would be able to find an update for both questions.

well u get after market kits that allows you to connect generic GPS devices - just add your SD card with map to it...
search the forum and you will find the links - it upgrades the screen to watch dvd etc.

I still have our 204 UMI to be updated (some complain that the update brings some issues while it does also bring a lot better maps) but the the USB updated would have to be PIN code restricted if it worked for one car only but the shops selling this update do not mention anything like this. Even in this case the USB stick itself would be reusable, one would have to pay for the PIN code (so why not get the USB stick too).
