Your post is great! I made a hardcopy and started to work.
Step by step it needs only 20 min to remove (and repose) the headunit, without breaking plastic brackets or cracks in the dashboard.
Otherwise it would take much more time to workout the disassambly procedure, so it´s easy.
Also the disassembly of the CAN BUS and screen from the frame is easy.
I resoldered the pin60, it´s real difficult to get a sufficient view to the micro solding points. I have an used single use med endoskope for enlarging. But nevertheless it is difficult to distinguish, if the joint is well soldered or if there is still a capillar-fissure below.
If there is an out of the factory problem with an isolatiation due to final covering, it will not be shure that the solder covers all .
After the first touch with the soldering iron (same 15w small tip as yours) I was not shure about. After 3x 0,5sec I rechecked it , it seems to be done.
I reassembled the unit, after rebooting the screen showed only a faded black white indication ,trip info without data.
Moving the topmost left multiconnector caused a normal operation.
It might be a PIN60 problem, which I repaired insufficient, or, another connection problem (crack or changing resistance) in the line from the connector itself to a loose pin anywhere . I had sprayed a small amount of anti oxydation contact agent to the female connectors.
At the moment the unit works, I will see it if it stays reliable.
If it fails again, I know the way to get again access to the internal parts in a short time.
In this case I will resolder each pin, or I give it to a electronic experienced friend to gauge the contacts and fix them.
Anyway your post is great help! Thank you!
