Go to bimmernav for availability and instructions on doing the nav upgrade.
I have an 00 and have done all the 'facelift' upgrades. Here is what I have done.
1) Upgrade 00 nav unit with 03 DVD nav unit.
2) Upgrade 4x3 nav screen with 16x9 nav screen.
3) Upgrade 00 headlights to oem hella angeleyes headlights.
4) Upgrade 00 taillights to oem hella celis tailights.
5) Upgrade 00 steering wheel to 05 M3 competition package steering wheel.
6) Upgrade 00 airbag to round airbag to fit new steering wheel.
The only thing I haven't done is retrofit the front PDC option.
