Just got a new 2010 Prius V with Nav and it has USB in the arm rest. It works great and shows all the song info on screen, but after about 8 min or so the iphone 1st & 2nd gen. time out, I think the phone goes into a sleep mode or some thing and the only way to get it to come back on is to disconnect the phone cable and plug back in. Is anyone having this problem too, can it be fixed? Thanks Jeff
