I bought a brand new USB stick, transfered music from my PC onto it, plugged it into my CX-5 and everything works fine. Recently I unplugged it to add more songs and it is now unrecognizable by both my PC and vehicle. Nothing shows up as connected on either device. This has happend twice now with 2 different USB devices. The dealer had no idea and didnt try very hard to find a solution to the problem. Anyone else have this happen?
