Looking for a Car Audio and charging solution, I would prefer to sit the iphone into something that will connect to the dock and will charge/play music. Currently I only run and AUX cable from my vehicle AUX port into the headphone jack. Is there a good all in one solution? I'm okay with 1 cable going into the dock then down the line splitting into cigarette lighter/AUX port. Anyone used this? Or similar products? http://www.griffintechnology.com/roadtrip I have read mixed reviews, am I just better off getting a separate stand and connecting something like this? Feedback with FM Transmitters? I am not too worried about Bluetooth voice, I can deal with getting a separate device. But I would like power and music coming over my car audio system. http://www.griffintechnology.com/itrip Any input is greatly appreciated.
