Hi all, I am trying to figure out what the factory equipment in my 2007 Grand Caravan SXT is capable of. The unit seems to be a RAZ code. It has AM/FM/CD/cassette & six speakers. I was looking around on MOPAR websites and found two add-on boxes that should allow me to add Sirius for about $170 (plus another $100 for the install kit). Two different dealers have told me the unit is $436. One qouted the whole install at $800. Nobody seems to be sure what I have! I called the Dodge "help" line and they were unsure what it would take to get my vehicle up to Sirius.They did say my radio code was razS - but did not know what the S is for. Can anbody shed any light on this mess?

Thanks,
John
