New to the forum. Comfortable feeling about both Alpine & Kenwood. My issue is one of compatability with Iphone 5. Virtually every time I plug into any of the current Head Units they won't work. Talked with Best Buy and they can't make it happen. Both Alpine & Kenwood have new models coming out next month. Alpine CDE-147BT, 148BT & 149BT and Kenwood KDC-x997, x897 & x787. They are all supposed to be updated with most current firmware. Any thoughts or ideas on which might work best from your experience?
