Re: 2017 Prius Head Unit
Honestly, I just went to Crutchfield to see what they said and figure out why they said it.
Then I went and dug through places like the12volt.com for info and/or wiring diagrams to see what the differences are.
While there wasn't much for a 2017 Prius specifically, the 4th Gen Prius spans 2015-2021 and I went and looked at what AV Infotainment options were available in 2017. Crutchfield's data is not 100% accurate either because they only list the Prius V and that was discontinued for 2017 in the U.S.
So if you have a Prius IV, that's confusing as hell because the V is not actually a Prius 5, it's a Prius Versatile/Alpha/+ and the regular Prius has the 1, 2, 3 and 4 monikers. They also list the Prius C as a "Wagon" when you select it and look at the option and the C is not a wagon at all, it's a short wheel base hatchback and the C stands for City.
So I went down a Prius rabbit hole trying to figure out what is actually sitting Phil's driveway and what it came equipped with. I thought the VIN would help but all it did was define the packages that were available on the different trim levels. Toyota had a tendency to make more options available for the same package on higher trim levels. I don't know if they still do it but it always was a pain trying to get the right part number for all the Toyotas we would get at The Greek's repair shop.
Anyway, it's like Uncle Ben said to Peter Parker, with great power comes great responsibility. I knew I could help and since Phil's, quite literally, practically a neighbor I'm in a unique position to be of even more help than I normally could.
Just trying to save a friend some time and money. My research took me maybe an hour because I know what I need to look for. Phil would probably still be looking or would have just gone to Suburban or over to see Angelo. At least now he can go relatively informed and knows what he's getting in to so things like sticker shock or lead times don't surprise him.

Re: Pioneer RT-71 R2R Maintenance
That's a seldom-seen Pioneer, for sure!
@SCompRacer it's -- arguably
-- too bad that I didn't know then that you were a tape deck whisperer... I'd have shipped this monstrosity to you. It did work but... well... kinda a charity case, you know? 

I never quite figured this one out. I think maybe TEAC made these for Matsushita aka National aks Panasonic... but I'm not at all sure of that!
Very large and heavy for a deck that "only" took 7 inch reels -- another odd duck deck from days of yore.

Why oh why does it have to be on the very east side of Nebraska...
Any closer I'd pounce.

Pioneer RT-71 R2R Maintenance
When I got this RT-71 several years ago, I replaced belts and bulbs and cleaned/lubed linkage. It recorded and played well and has sat around mostly unused. Now it has some scratchy pots and one channel cuts out recording in FWD, but it's fine recording in REV. It sports auto reverse playback and also recorded in reverse direction. No flipping tapes. It's a four head deck. Two erase and two heads that do both playback and record.
I have yet to find a complete service manual for the Pioneer RT-71 deck. I've asked at AK and Tapeheads forums. I even tried service manual pay sites. All I find is a few pages of PCB's and a schematic. No unit repair or calibration info.
I started looking at earlier Pioneer decks for a similar design. The Reel-Reel site has quite a database for decks, but they don't list all the early Pioneer decks. The first deck listed on the Pioneer page is the QT-6600 and the RT-71 is next. The blurb for the QT-6600 (Quad Track) said its based on the two channel T-6600. I was able to locate a service manual for the T-6600/6100. The tape head block and capstan/pinch roller are the same. Insides look the same. I'm thinking the electronics and calibration will be similar.

T-6600. Looks like it got a face job and became the RT-71.

RT-71

The pinch roller flips down out of the way and hides in the chassis for easy tape loading.

Press play and the pinch roller flips out and up against capstan.


Anyway, same old clean potentiometers and switches.

This deck has solenoid-controlled ALPS switches for switching between FWD and REV record and playback on bottom three PCB's. This one at far left side.

I had to remove one ground wire to flip the middle PCB around. That way I could better control applying DeOxit into switch without getting it everywhere. Lots of the old terminal post bare wire wrap in this deck.

Another short switch on the right side PCB.
