The iPod2Car (PXHCH2) connects any iPod directly to the factory car stereo system and is fully compatible with the 2002 Acura NSX. It provides users with CD Quality Sound, iPod Power and Charging, and Track Control from the factory radio and steering wheel. There is no better way to use an iPod in the Car.
How it Works
The iPod2Car (PXHCH2) connects your iPod directly the factory stereo system, giving you the CD Quality Sound you have been looking for from your iPod in the car. No FM adapter can compare to the digital sound quality of the iPod2Car (PXHCH2) "direct-connection" iPod car adapter. It is guaranteed to have absolutely no static or distortion.
In addition to the high quality audio, the iPod2Car (PXHCH2) allows you to control your music using both the iPod itself, as well controls on the factory car radio and steering wheel (if available). The Track Previous / Next buttons can be used to change songs on the iPod just as if you were pressing the track next buttons on the iPod itself.
The iPod2Car (PXHCH2) powers and charges the iPod so you never have to worry about charging your iPod before you can using it in the car.
All of the Sound, Track Control, and Charging are done from a single cable connected to the bottom of the iPod, giving you the cleanest and most discreet look possible. The iPod2Car (PXHCH2) works with any iPod that has the standard iPod connection on the bottom.
Installation
The iPod2Car (PXHCH2) plugs directly into the back of the radio in a 2002 Acura NSX without any cutting or splicing wires. You can install the adapter yourself, or take it to any local car stereo shop, mechanic, or dealership to have put in.
The adapter box itself is small and sits in open area behind the radio. A single cable runs from the adapter box to the iPod. This cable is very long and can be routed to wherever you would like to have the iPod in the vehicle. Any excess cable is stowed away out of sight.
The iPod2Car (PXHCH2) comes with everything you need to connect your iPod to your Car. No additionl cables or equipment are neccessary.
If you have a CD Changer located in trunk or glovebox it will need to be disabled to use the iPod.
