Another radio quitting problem

[simon]

Riding my bike yesterday (05) when I got off, I noticed the two front speakers not working. Played around with the fader but still nothing. Read up all the "speaker quit" posts on the site last night and disconnected the battery overnight.
Turned it on this morning, fronts worked for one, maybe two seconds then quit again.
This afternoon took all the tupperware off, and cleaned all visible connections (using switch cleaner), still no better. Disassembled the stingray to get to the connector at the back of the stereo unit (see pics), and after getting it off, sprayed it with the switch cleaner. Plugged it back in, front left working plus rears, took it off again, plugged it back in, front left no longer working!
I've tried all the connectors I can find, but it seems like I may have a duff unit! anything else I can try?

I've tried all of that and both my left speaker still don't work. I e-mailed Harman Becker and they said I needed a new circuit board. It would cost $400 for them to fix it and the parts are 6 weeks back ordered. I'm tying to figure a way to replace it with something better? I know you would not be able to use the controls on the handle bars but. I think a marine radio would work. You could mount a controler in the top where the buttons are. I'm still thinking. Moisture seems to be the thing killing the radios. I would have thought something better would have been in them.....

It's probably hosed. The speaker amplifiers seem to be the culprit when all else checks out. I too tried everything then tried this zany idea to deal with it...

As I have posted this before: The marine radio would be the ultimate answer for a motorcyle radio.
However, all control functions are gone.

When I had a Sea Ray it had a Maxima Marine AM/FM Cassette.
I was cleaning the boat and accidently preasure washed the radio.
There must have been a gallon of water through the cassette deck, the radio always worked fine.
Imagine if BMW used a radio with half of that quality.

Despite my best efforts with contact cleaner, the two fronts are still out. I've taken the unit (and control panel) to a radio specialist, he's going to inspect it tomorrow and report back. I'll post with the news then.

I bought my 2006 used back in July 2008 with 1100 miles on it. The radio did not work at the time of purchase and the dealer agreed to fix it as part of the sale. Turns out that the radio needs to be replaced (under warranty) but BMW no gots no steenkin' radios. Dealer re-assembled the fat girl and gave her back to me until he can get a radio; says they are on (inter)national back order.

Just spoke with the guy who has my radio. He says he's going to have to get in touch with Becker (UK) to find out the problem. He says it MAY be the main pcb, in which case it'll have to go back to Becker in Germany!
I can see this is getting expensive!

Thought so! My radio guy has been in touch with Becker who say the radio is under licence (?) to BMW and they can't work on it, only option is new/exchange radio which he says will cost £1,000 ($2000).
Luckily enough, just managed to find a company breaking a 2006 LT and have bought the radio off that for just £100!
