well after putting in 2 new alpine radios, i have taken them out and put the stock jensen back in. The alpine units would not play my iphone 4s, so i took them out. I tried the ida x100m and the cda 9886m, and neither would play my phone. I'm so over this whole thing for now. I also couldnt get the same "great" sound with them either. They both put out very little bass, and the remotes are too big to replace the helm one. I'm just going to call it good for now. the only problem with the jensen was that it would sometimes not play the iphone unless you jiggled the cable some, but i'll live with that after this weekend of mess.
