Bring it up again. 5 years later and this really helped; just did it on mine. Only did a reflow and it fixed it. Thanks to the OP!

 

I know this thread is old, but the problem with the display is still valid. I had to replace the bulb and couldn't believe the price that the suggested supplier was charging. So I did some research. The GM part number for the bulb is 16208443. You can check the price yourself and find it MUCH cheaper. But I went further and found an authorized GM radio service center who sold it to me for just under $2.

 

Best thread ever. It keeps on giving and giving. Just re-soldered the display leads and chip and the display is back and clear again!

 

OK not to bring up another time. but I am getting ready to resolder mine. Do you have to do anything with the theft loc before you take it out
????

 

This is an old thread, but my Monsoon every once in a while does not respond to either the unit controls or the steering wheel controls. Since the car is a convert and I live in Florida (where the weather is hot and the sun even hotter), I think I have to go in and check the circuit board(s) for cold solder.

It's only an intermittent problem and goes away most of the time. It does not happen when I start up in the morning, only when it's been on for awhile.

 

I think the problem was an iphone bracket that I was using. It was one of those that mounted into the CD drive. When the "problem" occurred, I removed the bracket and voila, the problem went away. It went away when I took the iphone off the bracket.

As best I can deduce, the weight of the iphone/bracket combination caused a downward pressure on the front radio panel, distorting something behind the panel.

Long story short, time will tell.
