Unless you read something such as a service bulletin or other people having the same problem, I would start in the trunk. A connector there is more vulnerable to mice, luggage, moisture, etc. Just because it's more exposed and can vibrate around more. The connector on the back of the radio will be held in place better but certainly can cause a problem too.
One more thing to not overlook is a connector in the middle of the car. Some changers can be mounted in other locations, such as between or under the seats of a minivan, and the standard cable is just long enough to reach the radio from there. An extension cable is used then to reach all the way to the trunk. Shorter cables are always better to prevent signal loss, and they're less expensive, so they won't automatically provide the longer cable unless it's needed.
I have a factory trunk-mounted changer in my Dodge Dynasty that plugged right into the radio. It actually came with the longer cable. A shorter cable could have been ordered. Seems backwards, but oh well. Ir works just dandy.
