First of, this is a great forum.
My problems is as follows:
Some time back, I had a auxillary box installed onto the radio unit of my 2006 Corolla CE. The aux-box allowed me to play the music on my MP3 player on my car speakers. It worked fine with no problems for a couple of years.
However, because of wear and tear, the wire which connects to the heaphone input on my MP3 player began to wear out (the 3.5 mm headphone jack was literally dangling on by a thread). The wire is a standard 8-pin Large DIN connector. The wire was replaced. No soldering was required - the wire simply plugs into the aux-box. It worked for several days. A couple of times, I heard a "pop" when I started the engine (likely due to the volume being set really high). Then after a few days, the radio and clock both stopped working.
What I have done so far:
1) I removed the radio and checked all visible connectors. I did not check any internal radio fuses (I do not know how). But everything looked OK. All plugs and connectors were tightly secured.
2) I replaced the DOME and CIG 15A fuses in the fuse box in the engine compartment and the fuse box located on the driver's side left kick panel. The CIG fuse was definitely blown. The DOME fuse was possibly blown. I could'nt tell because it had a lot of dirt on it. It was replaced anyway. I have seen on other sites where the DOME fuse also controls the radio/CD, so for this reason as well I replaced it.
The clock works now. But the radio/CD unit does not work completely.
Specifically, the radio does not turn on (I do not get any radio reception and the digital display does not turn on (the part of the radio that displays radio stations)), also when I select the CD changer (This option is available on Toyota factory radio/CD units. It is meant to connect to a CD changer that would be installed in the trunk of the car. The car did not come with a CD changer. So now the aux-box is connected to this option. When I select the CD changer, my car speakers play whatever is playing on my MP3 player).
But the CD player portion does work. When I insert a CD, it plays. Also the digital display displays standard CD information such as track number, time elapsed, etc...
I know I could just replace everything, but I am already $35 into this fix and I would like to see it work with what I have done so far.
Any advice would be greatly appreciated!
