Old head unit install on third gen questions

So I know this might seem ridiculous given the technology we have today, but I love analog format music. I've considered buying one these new old stock on eBay. It's the Pioneer FH-P5000MP. I believe it's one of the last big brand head units to be able to play cassettes. I don't even mind using AUX plus this unit is SiriusXM ready. I'm wondering, given the amount of harness connections the stock stereo has, if there's a harness that would convert all those to the old style single harness of older aftermarket head units. Do I look into the Maestro? I was under the impression that's just for retaining steering wheel controls, diagnostic info and truck options. I guess I'm wondering if this is even possible. I know also I would be losing my backup camera. Any info would be greatly appreciated. I think this head unit is really cool and would love to have it.

 

Critical tape deck listening is best suited for the house. Remember melted tapes, bulky tape cases, fumbling around? That’s all been solved now so you can keep your tapes in good condition and keep your eyes on the road.

Do yourself a favor and set up your tape deck zen garden in an unused corner of the house and get yourself a normal kick ass car stereo. That way you’ll have a nice quiet space to take in all that delicious tape hiss.

 

^^this…whenever I see a cassette I get anxiety attacks. I will never miss rewinding or fast forwarding a tape…the horrible quality sound everything. Sometimes to move on to better things we have to let go of older things.
Wow the only reason I still used a cassette player in my first truck was because I was too broke for a cd player.
I no longer use cd’s…step up to Flac or heck simple mp3 either through a thumb drive or right off the phone.

 

You can buy a wiring harness compatible for your truck to ANY aftermarket head unit. It's just a female end so you don't have to cut into your stock harness, but if you didn't care... you could even cut your stock harness end off and use those bare wires. It's a pretty simple color scheme for Toyotas, so it'd be easy to just patch over. Just 4 pairs of speaker wires (The tweeters are ran off the from door speakers), a power, and a ground. Not much to mess up. Your old head unit won't be able to use the advanced ECM features anyway, and nearly all antennae adapters are the same.

Just be weary of the fact that the Toyota antennae is powered, so you could potentially fry your old head unit if you run the power wire to your antennae, but on the flip side the antennae will not pick up near ANYTHING without juice running to it. I'm not sure how the analog/HD signals to your older unit would be handled anyway, so likely you're exclusively listening to those cassettes if you opt to move forward.

 

Maestro is only for Maestro compatible headunits.

I doubt that headunit has steering wheel control capability.

As far as Sirius/XM goes you're going to find the Tuner from that era and there's a slight chance it might not be supported.

You might be better off buying a newer single din head unit with steering wheel control capability and using this one as an "aux in"/source into the newer single din.

 

That would be a pretty funny configuration. And to your point on the Maestro, yea, it'd be a bummer to lose all those steering wheel and truck feature controls because you wanted a retro head-unit.
