Actually, thats not a bad idea for old/new model X5 (before the new X5;s that use HDD based navigation). In theory, you could replace the DVD drive w/a computer interface that would feed the Screen w/the appropriate info.

If BMW opened their source code, or published API's, this could easily be done. alternatively, someone would have to reverse engineer how to sit in the middle (between MAP info, and Car computer). This seems like a time consuming effort. If there was a market $$ for this, then it may happen in the future.

For all the vendors on this board, is something like this on your R&D plans?

Thanks
