Hi there, wanted to see if anyone has run into this issue before. I will preface this by saying that I did do the jumper trick to make my security code 6543, and I know that's likely the culprit. But perhaps someone else has had these symptoms and can help. My radio will be stuck on 87.something fm when I enter the code. It plays no music and wont change the channel. If I insert a tape it just flips between side 1 and 2. BUT if I leave the battery unhooked for about a half hour and then put it back together, turn on the key, and turn on the radio, it works fine! I enter the code it'll play and change stations. The tape deck does the same thing, but oh well. I can turn the radio on and off by the knob and it stays working. Then the first time I shut off the key it loses it and if I turn it back on its stuck at 87 again. Any thoughts?

 

While I cant say Ive heard of this issue if I read your post correctly that even when the radio is on if you use the cassette it jumps back and forth from side to side?

I always thought that if the radio was locked...well its locked and is inop. the fact that yours turns on and does weird stuff I would think the radio is just DOA.

IMHO unless you are into stock for stock sakes I would just replace the head unit with a modern one and call it a day.

 

Yes, you read correctly. With one exception where it turned on and worked until I turned the key off, it says code, I enter 6543, it unlocks, and its stuck on 87.something FM. If i put a tape in it swaps to the tape but just clacks around over and over saying "SIDE 1" ... "SIDE2" and so on. I do prefer to keep the interior stock, so I may take a stab at reflowing all the solder points inside, after all its already not working.

 

Does the Brown/Red wire on pin 11 have power ALL THE TIME??????
That is for the radio memory retain and without it the radio will default to 'battery disconnect'.

I'm not sure, but I just got it back in the dash yesterday. After a touch up on the solder, now the tape deck works, the radio doesn't, but it doesn't kick me to code anymore either. I'd say the unit is probably toast, but with the tape deck working, one of those phone adaptors and a radio app will do for now.

 

Hi. Tape is stuck in my player and the CD won't work 94 XJ12 XJ81)

 

I dont think I can be of much help, all I did was reflow all the solder connections I could get to inside, and that only got me partial functionality.
