i got my mom an iPod mini and iTrip for mothers day. it has been working fine until last weekend. she was on a road trip enjoying her tunes when the iTrip stopped working and she heard a normal radio station on the channel instead of the iPod music. i figured she just needed to find a different channel to tune it to, but when she got back and i had a chance to stop by and look at it i found that the iTrip was doing nothing at all. the light functions as if it should be working, but nothing happens. i have not found any documentation on griffen's web site. so the only thing i have tried is different stations and reseting the mini. i think i might have to exchange it for a functioning iTrip. any ideas or should i just take it back to the apple store?
