Yes. That's when the note comes up to check ignition and try again. I'm going to try a different adapter, may have a defective one. Also I know someone a bit away and may see if his setup works on my truck.
What I did, but not responsible if you do it. I stood a 28# bag of cat litter on the seat and used a ratchet strap under the front bottom of the seat and cranked it down until the seatbelt off turned to on. Ignition must be on. Now strap the seatbelt. Search a USB to your hearts content...
Still dirty, but got the Rough Country bed mat. Came rolled and is still not quite flat. Old bed rug molded and stayed wet too much. It was ok all summer at 104 degrees and no rain. Now I need a bit of heat to flatten the mat.
