Thanks. To clarify, the link references the Sony, but indicates it is a suggested replacement unit. If you look closely, there is a link for the Pioneer as well. Note, the Pioneer is a recent enough discontinued unit. As discussed in the intro post, the Pioneer is a double din DVD, non-shallow unit. Hence, I bought the comprehensive Metra installation kit, and understand that I will have to cut the top air box shelf using the template that is included in the kit, to make room to fit the Pioneer. Not worried about this. If I do it right, I will not lose any heater functionality through the front floor vents.
Minor Update: I will go without the LOC converter initially as no information I have suggests one is needed for a non HK, HiFi system. I have ordered another Scosche vehicle harness plug to salvage a missing SWC pin on the harness adapter I will use.
There will be a lot of wiring and adapters to contend with as far as stuffing everything behind the dash goes. Planning to tackle this project next week. I’ll update.
