Scion FRS T1819 Installed (Part Numbers and Pics Added!)

And it's Awesome! Got the T1819 headunit off of an FR-S Forum and splurged on the necessary wiring and bt mic. If anyone needs the run down of what you need I can post it but the headunit, radio (HD even, with the factory antenna), CD, bt streaming (a2dp), and hands-free calling are all working flawlessly in my '01 Spyder. Didn't have to cut or solder a single wire. The mounts worked and the only "mod" needed was some double sided tape as a spacer so the trim ring around the radio fit snugly (as the OEM is 2din and the Scion is Din+).

Edit:

More Installed pictures HERE!

-Radio/HD Radio

Look for the one with the same years as I have listed. The forum's upload limit won't let me post the ~8mb of pdfs.

Pics and post up the Scion part #s.
Incoming, will post side-by-side comparisons of the OEM and the T1819 as well.

Major improvement in sound, though i'm still playing around will the various settings the headunit has. The rest of the system (including the speakers) are to my knowledge original.

An added benefit is that the T1819 has orange backlighting which nearly matches the dash, way better than the old green backlighting on the factory HU.

Installed pics

Here are the installed pics of the Scion T1819 headunit in my '01 MR-2 Spyder. This headunit was boosted out of a 2013 Scion FRS and was the "base" headunit.

^If you look at it head on you can glimpse the double sided 3M tape I used to keep the trim tight around the headunit.
**Also note the top left, where I have mounted the microphone for the bluetooth on a switch blank (minimal filing on the blank onlyneeded to get it to work. No complaints from callers thus far.**

^there's a menu you can access by holding the volume button down with the hu "off" (but the key in the ON/ACC position) that lets you change the start up text.

The buttons and volume knob glow orange with the illumination on, and come very close to matching the main dash backlighting.


Here are the old and new headunit side-by-side:

Rear:

I'm more than satisfied with this install, the headunit provides GREAT sound, a modest cost of entry (the new wiring harness and bluetooth mic cost me more than the headunit did lol), and near-stock appearance.

Pro-tip:
-Leave the Car-type to Tc (best sounding to my ears) and play around with the SSP settings, I prefer the "Hear" mode.

Edit: Updated OP with part numbers and notes. I'll try to post some pics of the actual harnesses and side-by-sides of the old/new HUs soon.
Edit2: Harness Pics and night shot added in new post, side-by-sides added to this one. Mic placement noted.

PD - thanks for posting pics and part #s, so often the real info is overlooked :) With the cost of the unit and the cables, the unit is similar in function and cost to lower end aftermarket like JVC models. This unit probably has an edge on quality though since it is OEM.

Nicely done!

This writeup blows mine out of the water! :biggrin-new: Thanks for that shoutout and link to my thread. I have an 03 so I can't get my antenna to go up and down so I might get the shorty antenna. I agree the sound is phenomenal. When I settle into the new house I'll install an amp with MrsOnly's under-dash 8in sub enclosure. Are you adding an amp?

Great write-up. I have the same unit installed in my 2000. The predominantly orange lighting blends nicely with the dash color scheme of the Spyder. It is a good OEM+ upgrade and sounds much better than the 03 unit I removed. You can pick the HU up pretty cheap on EBay or the FT86 forum.

Thanks for the kind words guys :)
I spent enough time hunting through different threads on different forums and then hoping it would all work that I felt a single detailed post would be useful.

I don't intend on putting a sub in at this point but we all know how that goes, we'll see how much the lack of bass bothers me lol.

Here's a slightly blurry night-shot so you can see the color match for yourselves:

Here are all the things you need to make it work, laid out:

All the wiring with the packaging removed:

Bluetooth Mic kit unboxed:

How everything (minus the USB cable) looks when plugged into the new HU.

Previous posts have been edited to include details of the Microphone placement (I used the switch blank near the ignition cylinder) and side-by-side comparisions of the factory and scion headunits. Also added the scion headunit documentation.

I put my mic on top the steering column. When the top is down and I'm doing 65mph, I can't hear the caller (for obvious reasons) but I was told by callers that they can hear me loud and clear with minimal to no wind noise.

I can always move it, but aesthetically I'm happier with it on the dash rather than as a tumor on the steering column where I can see it :p.
It's a big mic compared to aftermarket units.

You have to move the antenna trigger wire in the second connector.
I have a 04 with the 1814 and that was the trick. The trigger is there but on another pin usually.
I'll look into it and post back as I've been looking at this head unit for Bluetooth/hands free.

Glad to hear there's a possible solution. Please post back when you find out wire color and the specifics on the second connector you're referring to. I'm in the middle of a move so I can't really get into my car at the moment. Thanks.

PureDrifter, Nice write-up. Looks like something that I may do soon. You stated that you have the original speakers. How did you connect them? Another question that I have is if I don't have an Ipod, it looks like I don't need PT546-00120-US. Is that correct? Thanks, Bob

The OEM spyder harness plugs into both the headunit and one of the adapter harnesses, hence the stock speakers work fine. You are correct in that if you do not need USB input then you can forgo the PT546-00120-US.

Thanks for the reply. The problem that I may have is that a previous owner installed an aftermarket radio in the car. I'll' have to check to see if the original harness is still there. Since the T1819 has connections for front and rear speakers, does the harness just give you a connection to the tweeter and door speakers and ignore the rear speaker connection? Thanks, Bob
