So, rather than get a RNS-E so the instal would be somewhat easy, as there is plenty of information provided, I decided to risk it and purchase a Kenwood 9980HD receiver. I could really use some help with all the parts I would need to make this happen. I also would like to rid the Amp as I have 2 from my previous 5000T. The navigation I see that it may need a special adaptor for it to work and the CAN-BUS as well. After looking at all of the possibilities for failure by purchasing incorrect of unneeded parts, I feel fairly lost at this point and any help would be greatly appreciated.
