My 2002 Boxster S has a 2001.1 Navtech disc in the PCM that's for California/Nevada. I checked with my local Porsche dealer and no updates are available for the older PCM's like mine but after some searching online I found that Vauxhall/Opel CD map updates will work as long as the drive in the PCM is 16 bit. Mine is and I'm just wondering if anyone out there knows if these Opel discs are available for U.S./Canada in NCDR format? If so I would love to get my hands on these before my trip out west this summer into the Canadian Rockies and then down into California wine country!
