Just an FYI ... there is no 2002 M45. It came out as a 2003 originally and there was only one additional model year sold (2004), before the new M was released as a 2006 model.

No, unfortunately. The OEM NAV unit has a bigger screen ... would not be cost-effective to rip out the entire dash and replace the screen, the full electronics, etc.
You would be better off getting an M that has it in already, or get one of the Garmin or Magellan after-market, portable units (also sold at Radio Shack of all places!). Magellan introduced a new model recently that is quite impressive. If you want more info, drop me a line, and I will look up the model number.

I have to admit, I have absolutely no idea! Hope someone else chimes in on this question.
