Thanks guys. So this would be possible for a 2002 as well? I know the 03 had a bit different setup. Honestly it will probably be worth it to me to pay upwards of $1500-2000 after factoring in recoupment from selling current nav, drive, etc.
Now we need to work on a parts list. If I get around to calling beno or cdan I'll report back but this will probably be a project with timeframe of about a year in mind for me so not rushing.
I have an 02 as well.
