I have one and love it!:thumbup: I was using the usb stick but once in awhile when I hit one of those mammoth New York style potholes it would vibrate enough to cause it to freeze up so I went to the SD card and no issues since then and I hit some good potholes too4:. It works great and I recommend it. :thumbup::thumbup::thumbup:
Be careful when you route the wiring harness from the left front of the trunk to the underseat connector. Space is very tight in front of the left side of trunk and under the trunk lid hinge. I laid the new harness on top of the factory existing big wiring harness that runs through that area and after a couple of days the trunk lid hinge damaged my new harness. That was a mistake.
I recommend you squeeze the new harness under the existing harness to protect it from hinge damage.
