I might be getting an IPOD or MP3 player as a gift this year and would like to use it in my truck so I am wondering what different types of connections there are for vehicles. I am not a fan of any type wiring hanging all over the interior, so I am looking for either wireless connections or something that can be easily hiden for a clean look. What are the pros and cons for these connections also. Do wireless ones still produce a good sound? I saw an FM tramitter type in Best Buy that looks to be wireless, does this type work good and produce good sounds? Are there better brands then others? Any help is appreciated as this is my first MP3 player and I don't know much about them. Thanks for all the help!
