RHR Radios all the same?
Couldn't find anything specific to tell the difference between the bus'. If you have the radio part number try going to a Chrysler parts dealer and ask if they can tell you.
About part numbers: Sales codes and part numbers for radios and discs can be quite confusing. A 3-letter sales code is assigned for each radio in a particular series. For each sales code, "RER" for example, superseding part numbers are assigned during the production history. Most part numbers start out with a series of numbers, such as "5064401". Revisions after that add a 2-letter suffix, as in "05064401AA" with later revisions followed by "AB", "AC" "AD" and so on. Revisions can consist of circuitry updates or changes, firmware fixes and changes, and minor cosmetic changes. In addition, sometimes changing a supplier for a particular part will result in an updated part number. In almost all cases the higher the last letter of the part number the newer the part. While parts with the same master part number ("5064401") are for the most part interchangeable with later revisions ("AA", "AB" etc.), there are exceptions in some cases. When upgrading to a new radio it is usually best to stay within the Master part number series that is assigned to your vehicle, as shown in the tables below.
Bus systems MyGIG radios run on two different Bus systems, a low speed Bus (CAN B) and a high-speed Bus system (CAN C). MyGIG radios designed for a high-speed electrical bus will not work on a vehicle with a low-speed bus, and vice versa.
