Hook up iPhone to Car?

I use an old school tape deck bypass , the kind in use by many back before CD decks were in cars. I hook up the jack on that cable to this and plug into the iPhone’s headphone port. Voila!

If you have:

1. a tape player: then use a tape deck (BEST VALUE)
2. an aux input: then use an audio cable (EASIEST IF YOU HAVE IT)
3. a radio: then use a radio transmitter (MOST PORTABLE)
4. oodles of money: get it done by a professional (BEST QUALITY/EASE OF USE)

hardwired is always better in clarity then fm wireless transmitters unless you like static. :)
