Okay I have a 2007 Honda Accord with the factory Stereo Installed. That means there's no usb port or not AUX headphone jack. The only thing this Stereo has is FM/AM/CD. What I'm looking for is something different than what I have thought of below, if there's anything else, so that I'm able to listen to my Iphone 4s over my car stereo. I would prefer the cheapest and easiest way possible.
I'm aware there are FM transmitters, I have bought the ones that are $20 and I have bought the ones that are $150, all of them sucks due to interference. (yes I also bought the interference canceler thing and it did nothing.)
I'm also aware that I could buy a new stereo for my car that has a USB and/or AUX headphone jack, however, I would much rather not do that because I drive a 2007 Honda Accord and I would have to spend $200 to by the new dashboard insert that will even allow my car to have a stereo harness inserted and with the cost of the new stereo, stereo harness, and custom dash board I'm looking at over $500 easily.
Please Help I NEED OTHER IDEAS AND OPTIONS I HAVE LOCAL STATIONS AND WASTING TIME AND MONEY MESSING AROUND WITH BURNING CD's LOL!
