My original dealer (Frederick Caddy in Lebanon, PA) quoted me $5,000 to install the DVD nav w/10 speaker Bose.
Related, the service dept of my local dealer (Towne Caddy in Jersey) stated that it was not possible to upgrade the Bose 8 to Bose 10 w/HDD but no nav due to wiring harness issues. I would think it is probably the same deal going from Bose 10 w/HDD no DVD nav to DVD nav.
Read the posts on those who tried doing this. Hope you are talented at all the rewiring and adjustments to be made w/o any documented procedures. At one time I wanted the dealer to do this - going from Bose 10(standard with Perf. package) - with no luck. If you have a Lux model with base radio(RPO U2T/Bose 8) it would seem impossible.
