managed to come into work early today and take my 2015 8.4 out to try out the 2020 8.4 68461704AC
needed to purchase and antitheft code. it cost $11.30 cdn from
www.carstereocode.com and it was emailed to me in about 5min. odd thing is that the recycling yard that had it listed said it was a nav unit. the part number tells me it's not a nav unit. when doing the carstereocode lookup I selected non-nav and my part number didn't come up. changed to nav and the part number was listed. weird.
I plugged in the 2 connections that were connected to the old 8.4 and the large main black plug as well as maybe the hub (with the mini usb looking connector) ? there seem to be a few more spots to plug things in and I don't have the plugs lol
obviously it doesn't recognize the hub.
after 10 -15min all of my options started working and appearing accessible on the screen. yay
