    Original car firmware was 59.0.441A. I instaleld AIO 2.8.0 and AA 1.09 and was having USB connection troubles, it worked 50% of the time. Most of the time after a few successful connections it would stop working. However, rebooting the CMU by holding the 3 buttons for 10 seconds would always...
