Audi A4 S100 vs. ?????

Hi,

first, excuse me for my english, but i can't write or understand french. (i'm spanish )

I'm searching info about S100 platform for an Audi A4 2013, and i'm interesting in a Android or WinCe 6.0 Gps Nav.
the RoadNav S100 appears as valid and good nav, but i need yours impresions.

This appears as new in european market, but can anybody tell me how it works in Audi? It's similar to VW integrations with CAN-BUS?

Thanks.
