To start off, my car doesn't have an auxiliary input, it doesn't have a cassette slot. So the simple way with a tape-to-3.5mm jack/ or a auxilary cable doesn't work for me. I want it to charge my 4th gen Ipod nano and my iPhone 3G. I'm also planning to get the upcoming iPhone 4G. I've used FM transmitters before but the receptions are pretty bad at times, and they go outdated when i get newer apple hardwares. For example, i had a Monster iCarPlay but it wasn't compatible with my iPod 4th Gen and had limited functionality with my 3G. so i had to replace it with a Belkin one but the reception were a lot worse than the monster one. I've recently lost my Belkin FM transmitter so i'm looking for an alternative way to play music in my car If i don't want FM transmitters, is car decks then only way to go? I need it to be able to play audio from my phone because i do use iphone GPS apps as well as musics, I also need it to charge my iPhone/Ipod ANy good suggestions?
