Ok so I'm new here but you guys seem to be pretty knowledgeable about your cars So I'm driving a 2008 liberty sport and it really bothers me that I can't control my volume etc on my steering wheel. so I would like to buy a limited steering wheel. would anybody foresee any problems with this. I was think about purchasing the steering wheel from here: http://chryslerjeepparts.com/jeep/liberty/2008/steering-wheel/steering-wheel-trim/steering-wheel/

I figured there also wouldnt be any electrical equipment standard for audio controls so buying this would be necessary: http://www.newegg.com/Product/Product.aspx?Item=N82E16882461044&nm_mc=OTC-Froogle&cm_mmc=OTC-Froogle-_-Car+Accessories-_-PAC+Audio-_-82461044

just for reference I have a pioneer aftermarket head unit

Also does anyone have pics of the different limited steering wheels ie the one w/ cruise control and w/o

Thanks for everyone's help!

I wouldnt know about adding the steering wheel but to add aftermarket control Metra is a better company than PAC. I had PAC in my scion and it had quite a delay, switched to Metra and delay was gone and it is auto install.

As for the steering wheel unless someone has done this swap you may be on your own. The wiring for the steering wheel controls would need to already be present in your vehicle just not obviously connected to anything.
