What's the best way to connect my nano to my radio?

They don't necessarily need to be close to the radio, Lane. Instead, the quality gets affected on how close your car antenna is. Personally, being the crazy "give me all the quality you can get" music guy, I prefer not using my ipod with a car - as my car radio reads mp3 cds. All the quality for a little bit more trouble.

I would change my mind if my radio allowed me to connect to the ipod using the ipod connector. Oh yes, that would be sweet.

I just ordered the i-honda R3 from http://www.icarkits.com/index.php. Installation is super easy and uses the ipod connector

The best way to connect a nano with your car radio is with a wire. I got the Griffin FM transmitter and at least in the Bay Area, it sucked -- lots of interference.

I had my car broken into recently and my radio stolen and had to buy a new one. I got the one of the lowest cost radios, but it had an AUX connection, and I spent $8.99 on a Ipod Dock Conn To 3.5MM Cable. Works like a charm.

Here is the amazon link http://www.amazon.com/gp/product/B000...

This works well, but doesn't charge the ipod or allow you to control it using the radio

True -- there was a radio that I could have bought that would control the iPod, but that was mucho bucks more.

I personally hate wires, I was about to recommend a product by "Xtreme Mac" which included a charger and either an FM transmitter or a cassette adapter but apparently they no longer make them (I paid $6 for my kit which usually sold for $19.99). As for my experience with the Xtreme Mac FM transmitter, It is a good product as long as you have a clear FM channel to tune into. Else you will get all kinds of signals no matter how close you have your transmitter to the radio. I found that on mine it worked better if you had the unit close to the radio antenna. (if your car has one)

I agree with Tim, a wire is the best choice for the best sound. I tried it with a Dodge Caliber that had an Aux port on the front and it worked good but not great the sound wasn't that clear(I think that was because of the stock 4 speaker audio system in the car and I was also driving in a 10 lane highway rush hour time)

If your car supports bluetooth then you can also connect your iPod that way. Bluetooth is the best way I have tried so far. As for adaptors I have tried Jabra and Sony's bluetooth units for audio transmission. Economic solution would be the Jabra, Sony's is a little over priced in my opinion but it has great sound and you can toss the ipod on the back seat an still get awesome sound with no wires or FM interruptions.

So, anyway to go back to your initial question, the best solution depends on your budget and what your car supports. I have tried wired, FM and bluetooth and all of them "work" fine. If "sound" is your thing then go with the wired or bluetooth solutions else try the Xtreme Mac FM transmitters.

Good Luck!
