Hello,

 

I currently have a bypassed x920bt installed in my car. I also use the aswc steering wheel control unit. I'm looking into upgrading my Headunit to the new z140.. Will the z140 be an easy upgrade? Simply plug and play with my current harnesses and wiring? or will I have to redo everything.. Reprogram aswc, new bypassed harness, new nav antenna, new mic wiring, etc?
