I did some more research in looking for my Crossfire Infinity radio information.
The name Infinity is only the car's name for the radio. On eBay I found some of
these radios for sale, but very few with the NAV option. As I looked at the photos
on eBay, I found the manufacturer, type, and model numbers. The manufacturer
was Harman/Becker Automotive Systems, Germany. The type: ZH 29, model:
BE 6811 (for the NAV) and BE 6806 for the standard rado. These radios were built
specifically for the Crossfires, so there are not many of them around, except for the
recyled ones. I found a sorce for repairs, Becker Auto Sound LLC in Saddlebrook,
NJ, phone: 201-773-0976. They advised me that no schematics for repair were
available. I was told that similiar radios were made for Mecedes, and Porsches
around 2005. Even though I had removed the fuse to "reset the Radio" that did
not work. They suggested removing the rear radio connector for a reset. I had to
order the two keys for the lower slots to remove the rado from the dash. They
cost $ 4.00. I did it and the radio problem cleared.
