OK, I'm no Adventure Rider (ST 1100), but this forum appears to have the most knowledgable folks with repects to the Garmin 2820. I purchased a unit off of Ebay back in March and it appeared to work fine. In June I decided to get an XM Radio subscription and when I tried to activate I got a "check XM antenna" error message (the unit recognized that I was plugging and unplugging the antenna) and could not get to the XM screen on the unit. The unit did not come w/ a power convertor so I finally purchased one and when I tried to connect to my home computer I realized that the mini USB jack must be bad because the computer would not recognize the unit. The bluetooth feature appears to work fine. The USB cable does to appear to be looser than it should be but I cannot detect any wiggle from the USB jack itself. It was too late to try for any resolution through Ebay or PayPal. I have a couple of questions: Does the unit connect to a PC through a standard USB Type A plug/5 pin mini USB Type B cable or is a Garmin cable required? Garmin will do a out-of-warranty repair a 2820 for a flat $170 no matter what is wrong with it and warranty for 90 days. Should I do this or shop for someone who will quote just the USB repair since I am pretty sure that is all thats wrong? Has anyone devised or found an adapter plug or pigtail that can be left in the jack to protect the unit jack from the constant plugging and unplugging when switching from GXM30 and USB cable when storing music, etc? Thanks in advance, Avenger in Greenwell Springs, LA.
