Hi Everyone :-)
I have owned my crossfire for about a year now and love every minute of it. Unfortunately the only thing i do not like is the stereo head unit. Lately its been not playing my cds and makes a weird clicking sound. It also doesnt want to give me my cds back unless i give it a whack. This is a perfect time for me to get a new headunit. I have my eye on a sony cdx-f7750s. I used to have one in my old car and it was great and because its silver it will also complimemt the dash. I cant find much info on installing a new headunit. I came across a few posts but it involved connecting different wires etc. Now as im lazy that seems to much like hard work
What i want is a wiring harnes that i can plug the new head unit straight into the cars connectors. There seems to be quite a few around but when digging deeper it appears that they wont work due to the car having an amp etc. I found a site that has a harness that uses rca connectors so the stereo runs through the amp so the sub and speakers all work. Is this the right connector. Link ---- Parts for 2005 CHRYSLER CROSSFIRE - photos, charts and more installer.com it is the harness call the alt harness.

So what i want to know is:
1: will the sony head unit fit in the crossfire
2: the head unit says it has rca inputs outs at 4v, is that enough?
3: is the harness the correct one, if not do you kmow of one?
4: as you can see the harnes is from a USA site, so will the connectors be the same as the UK fittings. Yes dumb question i know

I would really really appreciate your guidance on this.

Thanks again
