I am planning to upgrade my HU (I can't stand the stock HU). I have PS2 on my navi and I am thinking of getting the TV Tuner. I either want to somehow feed the TV Tuner into the navi screen with the PS2 (I'm not exactly sure how yet) and get the new alpine HU with the larger face and move my EQ to the dash also. My second idea is to buy an indash screen and flush mount it in my dash and get a changer and hook the tuner up to that. What do you guys think I should do keeping in mind costs also. Peace.
