It's about time I weighed in here...

The Beat-Sonic TVK-54 has 24-pin connectors. It will not work with the Fujitsu Ten nav HUs in 2012-up Impreza and Forester, and 2013 BRZ and FR-S.

  • 2010 Exiga
and a similar OEM Kenwood satnav, used in
  • Some 2008-2009 Legacy/Liberty/Outback outside North America
Although the back looks similar, the nav in 2010-2011 Legacy/Liberty/Outback does not have the parking brake signal on its 24-pin socket.
From the above posts, it sounds like the BRZ's nav does use the parking brake signal to disable video display while driving.

However, I seem to recall a 2012 Impreza owner with the Fujitsu Ten nav (model FW602US) saying that grounding the parking brake input did not unlock everything that is disabled while driving.

An easy way to verify is to pull up your brake lever just far enough to light the BRAKE light on the dash. Then have a passenger look for things that are still locked out while you're driving.

We theorized that the FW602US was also using the speed signal (VSS) to detect motion for the lock-out. A simple way to test that is to just unplug the 28-pin harness. You'll lose your microphone and aux input, but you should still be able to test everything else.

I've seen BRZs with model numbers FA601US (here) and FM601US (here). Does the FR-S have the same models?

The pin-out tables that xcelir8brz posted are for the 2012 Impreza Fujitsu Ten nav, model FW602US, from my NASIOC post here. (I'd appreciate credit and a link)

There are several differences in the BRZ and FR-S:
  • Model number (on front) is FA601US or FM601US (Impreza is FW602US)
  • FR-S and BRZ do have speaker amp remote turn-on (used for the amp for the door speakers)
  • FR-S Does not have power antenna control on the 10-pin harness. BRZ does.
  • Antenna control for the FR-S is on the antenna connector (blue wire on the aftermarket antenna adapter), for the antenna booster amplifier. BRZ does not have that pin on the antenna connector -- uses wire on the 10-pin harness.
Possibly more differences (I haven't seen Subaru's wiring diagrams yet). Does anybody have them they can send me?

And can anyone post pictures of the back, factory harnesses, and the label on the top?

I just cut the grey wire on the 16-pin rear camera socket (i.e. where the e-brake lead is), and extended the wire from the stereo side connector to the above pin 7 and electrical taped the far side grey wire so as to not short out anything.
Are full phone functions available while driving shorting the ground like this?

You've got credit! This helped me out as well and I apologize if this is a repost, just a bit easier for the audience to view.

I grounded the grey wire as mentioned earlier, the movies still played while the parking brake was down, however the screen turned blued as soon as went passed 3 mph. Did I miss something?

Try unplugging the 28-pin harness and see if video works.

I did not take pictures. I can take pictures this evening when I get home. However, it's extremely to do this little project.
- remove the right panel using a flat screw driver (or use a tool with a softer flat surface to be safe)
- remove the left panel
- use a 10mm socket to remove the 4 bolts holding the HU
- pull the HU an remove all the plugs
- There is one plug with only 1 wire, which is grey. That's the one that we are suppose to ground..

I will work on it some more tonight and I will take pictures if you still need the visual aid. Just let me know before 6pm central time.

Im taking it apart right now. Saw the grey plug. Now finding the wire with which to ground it. I just cut the grey cable, and cut the ground on the 10 pin plug, and connect them toghether?

The pink wire is #7 on the speaker plug correct? That is the one I have to shorten the gray one with?

No... hold your horses... I dont think it's pink. I think its black with a slight blue line down the center ... take a quick picture of it..

You don't need to mess with the ground lead on the 10-pin plug. You can simply connect the HU's parking brake lead to chassis ground -- use a screw on the rear or side of the HU.

You can ground the wire to anything, I just liked to keep it clean on the 10-pin plug. No obstructions for sliding the HU back into the HU frame. A screw on the rear side of the HU may work, I couldn't do it on the side due to clearance issues.

I tired one of the bolts that holds the Unit, no dice. Still blocks out phone functions like dial pad dialing. Tried that screw on the last picture, no dice either.... The ground on the 10 pin connector, I need to cut it then connect with the gray one?

cut the grey wire. tape the side going to the front of the car. with the grey wire hanging from the connector, add a wire to that grey wire and solder/tape. next, take the end of the new wire and ground it to 10 pin connector, pin 7 (on your car it looks like a pink wire), on my BRZ, I think it was black. you can also tell if the grounding works by going to the diagnostics menu under settings, and watch the screen with (r)everse, (p)ark, etc.

You can also find a screw on the back of the headunit, and ground the grey wire there. It needs Chassis ground. OR add a really long wire and find a nut/bolt on the car somewhere behind a panel and ground it there.

Where you ground it is not chassis ground (left of head unit nut) image 98.jpg.


10-pin power/speaker harness
1 2 - - 3 4
5 6 7 8 9 10
(orientation: viewing pins on car's factory plug, wires pointed away from you)

Code:
1 RF+

3 +12V Accessory
4 +12V Battery/Constant
5 RF-
6 LF-
7 Ground
8 Power Antenna (provides power to Subaru's antenna booster amp)
9 [NC] {amp remote turn-on signal on Toyota HUs, not Subaru}
10 Illumination+

Yeah, screws that go into plastic won't work.


Thanks for posting those pictures! Looks like the radio in your BRZ has leads for both power antenna control and amplifier control on the 10-pin harness, and no power antenna wire on the HU's antenna socket.

What is the model number printed on the front of your HU?

Can you take a picture of the top, showing the manufacturer's label? (that will have several model numbers and an FCC ID).

I figured as much on the screws, but I said what the heck, I don't see any close by so I'll use them :-) I'll continue tomorrow and will take the pictures.


Thank you guys for real, and pardon my ignorance

So David, (I'm David too by the way!).

You can confirm that my ground is the pink cable? I will first try to find a ground screw in the area. If not, I'm hooking it up to the ground on the 10 pin. Initially I did not cut the pink cable and connected the gray cable with it, I just put the gray cable on the connector connector and apparently it did not do a good connection. I used to have a multimeter to check the ground location but I misplaced it and have not needed it since. I'll buy one tomorrow.
