Radio cassette player replacement

I was trying to use a cassette adapter to play my iphone thru 2001 300 m sound system. The adapter would not eject, so I pulled the radio out and finally managed to remove the adapter. When I connected the radio back, the power would not come on and I also lost the use of my power door locks and my hand held door opener...I've checked the fuses, the amp. Nothing is blown. Anyone have any ideas??? Anything would be helpful...right now, I'm thinking of just replacing the unit with a new one...thanks for any help..

Before you replace it make sure you check ALL fuses AND relays, if those are good make sure the wires in the back didn't come out of the plug or didn't scrape against anything to create a short when you took it out of the dash.

I pulled it out again today to check with no luck getting it to power on..their are 2 7 pin harnesses on it...one black one grey, do you know which side goes closest to the outside? thanks for the help..

Good question, I'm not real familiar with 300M's. Is there any difference at all in the connectors? Can you interchange them and plug both connectors in to either slot in the radio? If you can then switch them around and see if it works then. If they are interchangeable then either it's gonna work or not, you won't burn anything out. You should always pay attention to things like that so if connectors are the same then you don't get them mixed up

yea, I should have paid more attention...and I had my camera with me but forgot to use it...anyway, I may try switching them around...I don't think I could blow out anything else...thanks..:banghead:

FSM doesn't really help with black/gray issue. It shows the two connectors, but not which side each is on. The gray side has the #7 pin going to the battery (pin away from the little "L" end).

Those connectors should be indexed so they will only fit the socket they were designed for.

Thanks for all the help...Got it done...it was a different blown fuse.:grinyes:
