Since the GPS disks that came with all of the Crossfire Navigation Radios are dated May, 2004, and will NEVER be updated by Chrysler because Corporate Chrysler has no idea who is even in charge of that department. NavTech (now NavTeq) is unable to produce any of their usual yearly updates because Chrysler retained the permission to update the Crossfire disks.
Navteq told me that that they believed that the GPS radios most similar to the Crossfire ones were in the 2005 - 2008 SLK Mercedes that were produced 1 row over at the Karmann factory in Germany. Apparently the SLK had a CD player in the dash and a connecting DVD player in the trunk. The SLK GPS system operated utilizing a single DVD placed in the trunk. The data is in the .DB extension format used by NavTeq in both the SLK and Crossfire. The Mercedes DVD disk contains GPS info for the entire United States and Canada, extending from Alaska and Hawaii down to Puerto Rico and the Virgin Islands. This DVD is dated September, 2009, and will be produced yearly into the foreseeable future.
Does anyone on this forum have the technical computer skills to separate the Mercedes .DB data files into separate updated .DB East and West US files that could be placed on updated CD disks for the Crossfire? If a person studies the file content of both the Mercedes and Crossfire GPS disks, the similarity of the geographical data files (3 separate ones on the Mercedes disk) is apparent. The specific car and radio GPS fies are separate and are very obvious. This DVD contains too much data for one CD. If anyone has the skills necessary, I can transmit the files free for study. This DVD costs $ 281. Also, this forum has a link to the Crossfire East and West disk contents for downloading, in case anyone wishes to study them.
Certainly some roads have changed in the U.S. in 5 years!
