I have a friend that has a radio shop. He has a 430 RBZ (non-nav) that has the green back-lit buttons. It's in great shape, from a dodge truck. I plugged it into my jeep, and it works great, even switched to Jeep in about 1 minute.
He wants $300.00 plus shipping. If you want this, let me know, and I'll get you the deal.
He actually has two, but you only need one......
