Re: The CD has quit playing and an ER 4 message
I had it too. - when I bought the used vehicle and was elated that it had a Jensen sound system in it. The sound was good - played a CD the first time I put it in. We listened to the radio after an hour and then attempted to replay the same CD. The ER-4 message showed up. The man who sold me the vehicle had given me the paperwork on the unit and I reset it. I've had to do this at least 4 times which means you have to reset all your favorite stations, time, etc.

It is quite possible that your Cd has a faulty optical head which does not read the data from the cd. Hence the error message. What you can do is to clean the lens of the optical head and try again . If not then you will need to replace the head but seek help if you have not attempted any electronic work as there are many delicate details to follow with the replacement specially with the solder short on the new unit.Also to evaluate the cost of the new unit is also required. Hope you try this out. Good day
Check and see if there is a fuse on the back of the unit if so check it
to make sure that it is not blown. Also make sure that it is at
least a 25 - 30amp fuse. If that is not it the make sure you have the
power wires hooked up right. See a Er-05 message means that the power
that that unit needs is not there. So it will not read all cd's. It
takes more power to read a burner than a normal cd. Hopefully this helps
