I suppose you're against ppl attempting what is essentially a basic repair because of the potential for collateral damage thru inexperience? However, it's not hard to find information on how to safely open a particular Garmin device and then even if someone doesn't know how to solder it's not rocket science to learn or just get it done by someone else like the guy in the second video. If you wouldn't do it that's fine of course and the OP may-well also decide not to attempt repairing the socket which is also fine. He can now make a decision armed with the information of how to at least investigate his device's problem, or leave it how it is now. Most devices with this problem don't need the socket replaced, they only need the connections repaired.
