My Radio is possessed

[isail1]

I can't seem to get my radio to work. My car is a 2003 Boxster and the radio is original / stock.

My radio has worked perfectly for over 8 years. The problem started when I recently replaced a dead battery. At that time I also cleaned the "battery area" of pine needles and dead leaves; I used compressed air to blow the junk out.

The radio will occasionally turn on, and then unexpectedly turn off. If I unplug the associated fuse and re-plug, the radio might work for awhile and, then again, it might not. I have tried everything that I can think of to fix this problem, including......

- checked the amps; with fuse removed, mA are about 50, with fuse plugged in, mA increase to about 80... I don't thing this is unusual

- I replaced the starter switch...no difference

- all fuses are OK

- I checked all wires that are visible for any type of problem.. I can't see anything

- I pulled the radio and removed the faceplate to check connections...no difference

- all other electrical items on this car work perfectly and I do not have any aftermarket alarms or dodads installed.

I am at my wits end with this one and can't think of anything else to check. That being said, is there anything I might have missed? For 2003 models, is there some type of radio re-set procedure using the Porsche diagnostic computer? Lastly, if I must buy a new radio, are there any recommendations? I would want the "new radio" to be an exact match to the current black matte finish.

many thanks in advance

When you say "starter switch" are you talking about the ignition switch? The ignition switch would be my first guess. If you've already ruled that out, not sure where I'd go next.

You have to have loosened some connection with your maintenance is my theory. Do you have an amp in the front trunk near the battery? Did you disturbe some wires/fibre going between units? Connections at either end?
