I'm not too crazy about the mach 460 so I'm looking to put in a Pioneer head unit. What will it be compatible with and what will have to be bi-passed? I'd hate to have things go to waste and would like to utilize everthing expect the stock head unit.
If you have a 98 and below, you can put a difference head unit in, no questions asked. Trust me. I've done it. Goto walmart and get a scosche wiring harness for your car and plug it in and wire it. Works great and sounds great.
I've swapped my head unit to...go to the sound and shine forum and do a search on Mach 460...It should pull up numerous threads on the harness and line adjuster you need.
