I don't have huge expectations, but I figured I'll ask anyways....
When I got my Eclipse HU, I set the security feature with a "Key CD." I have since forgotten what CD I used to enable the security feature.
I had to disconnect the battery yesterday when I was doing my gaskets and now of course I cannot use the radio. Anyways, I have to send the HU back to Eclipse for them to "reset" it so I can use it.
I'm curious if there are any experienced people who know what it is they do to reset it so I can avoid tearing it out of the car and paying them to do it (assuming they charge for this service). If it does not involve replacing anything inside it, and/or it is easy I'd probably try it myself. Are there any electrical experts that can LMK?
