I appreciate you getting the information for me. I found the installation template for the 205 and the 670 appears to be using the same cut out and drill holes so I am going to go ahead and order the 670 from Crutchfield this week. Not 100% sure if the transom remote is compatible since fusion has come out with an updated version of what I have but we will see. The tech notes say that it will connect to any NRX wired remote. At this point just looking forward to some tunes on the boat and not having to go through some significant modifications for another head unit.
