I have an opportunity to pick up the AVIC-F90BT, all the wire harnesses (steering wheel control, bose adapter etc) for $599.

 

Or I can pick up the AVIC-X910BT for $549 and pick up all the harnesses on the side, probably $100-$200 more for those.

 

What do you guys think?

 

Edit: Or I can get just the AVIC-F90BT for $450. No harnesses
