I would agree with your wife - you probably would sell many of those dash pieces if you posted them on a Jeep forum... the question is do you have the time and would people be willing to pay what you think your time is worth.
Might want to post your OBD comm issue on the Maestro forum. They are very good about responding in a timely manner and others can see the issue and solution. Matter of fact, I think someone over there posted a similar issue in the Jeep secton: http://www.12voltdata.com/forum/viewforum.php?f=351
Were you able to use the Jeep OEM bluetooth mic with the Kenwood or did you have to use the mic that came with the Kenwood?
