will the Scion 6-CD/mp3 HD unit work on SR5-sport with Audio System 3 thats:
JBL AM/FM CD Cassette
Steering Wheel Audio Controls
Rear Audio Controls
10 Speakers
2 Sets of Wireless Headphones
You can upgrade to an aftermarket headunit with MP3 capabilities. I think there's an adapter for the steering wheel controls you can use with aftermarket units, though I'm not positive. I think it's made by SWIX or something like that.
Yeah you have to go with an aftermarket stereo, or hook a ipod up to your jbl system. I have told all my friends who bought the 4runner to get the stock radio, then upgrade. They are all glad that they did. The Scion HU rocks....
