Missing wires

Bought this harness to install an RB1 navigation unit in my '01 Durango R/T. When the ad copy says it replaces a factory harness that's not quite true. It'll work fine if you don't have steering wheel controls, but if you DO have steering wheel controls, this isn't the harness for you as two critical wires are missing. I found this out the hard way and ultimately had to order a Mopar harness. Had this been noted in the ad copy, I wouldn't have wasted my money on this and another harness, not to mention the time spent soldering and shrink-tubing the two into one.
