About 3 months ago, I installed the Grom i-pod integration for my '04 Mazda 3 hatch. Until today, I've been very pleased with the purchase. Now my head unit will only switch between FM and AM, does not recognize the CD player nor the mode I use for playing my i-pod. This may be coincidence, but I was wondering if anyone had any ideas on how to fix this. I have not yet unplugged the battery to reset everything. Thanks in advance for any advice!
