Aftermarket Head Unit replacement questions.

Ok here's the deal. I have 2010 JK unlimited with infinity stereo system (No steering wheel controls). I'm looking at putting in a JVC KW-V20BT. http://mobile.jvc.com/product.jsp?mo...hId=133&page=1 Now I have searched around here and other JK sites for information on replacing the factory unit and I still have some confusion and questions. You want me to build a computer and I do that in my sleep, but modern car stereos confuse the hell out of me.

1. People talk about needing and not needing a Metra (or other) harness. http://www.metraonline.com/part/CHTO-03 Do I need one to maintain factory functionality?

2. I've also heard mention of an Antenna cable adapter. I do listen to the Radio so am I going to need an adapter there as well.

I'm sure that I'll have other questions down the road,but that's it for now. If anyone knows of a link to detail instructions on this, I'd be happy to see it.

Thanks.

Whatever stereo you buy will include a harness which plugs into the back of the new stereo, and will have pigtails on the other end (just end with wires, no connector). You would have to cut your factory harness connector off to use only this, so the best thing to do is get a vehicle specific harness (Metra or other) that will plug into your factory connector and end in pigtails on the other side. Simply connect this harness to the stereo harness and you're in business.

It's possible you would need an antenna adapter, but I can't say for sure. A site like crutchfield should be able to provide you with a list of all needed accessories to complete a stereo swap on your Jeep (and they often even have step by step, illustrated instructions available).

Hope that helps.

Same opinion on Crutchfield here too.

They also had to provide some troubleshoot support on my install even with the specific harness cause I didn't have sound for some reason. They were able to help me find and fix the problem.

Thanks for the advice guys. I looked at Crutchfield and think that when I eventually do this I'll be talking to them.

It all depends on what you want to do. You will need a euro antenna adapter. If you want to use the factory amps that is one harness, and if you want to add your own amps you will just use a 2007+ harness for the ground, Battery constant only. The Ignition wire will have to be run to the fuseblock or tapped off the Lighter for the exit delay to work. If you want steering wheel controls to work, you will have to get a head unit that supports the peripheral harness or whomever makes a steering wheel module. Some head units have a specific plug in for them....Pioneer being one of them.
