OK, really off the wall ? here. I bought the phone holder that goes into the CD slot of the radio, then I went to Wally World and bought a USB charger that goes into the cig lighter to keep my Iphone charged while playing my tunes or using my GPS. Problem in it seems as if the charger that goes into the lighter seems to not go in deep enough to make contact with the middle contact. What USB charger adapters are you all using??
