Where is a good source for a Palm OS OBD. I got one of the good 06s that will let you read codes in the odometer window. But the wifes 06 Liberty CRD won't let you do that (thanks D/C). CEL light come on the CRD the other day then disappeared. Dealer gave us the "I don't know, can't duplicate" thing. Would like to be able to read codes and have a Palm T3. Suggestions???
