BRZ NAV/DVD bypass
 

Not sure if this will work with the BRZ nav system...but it works with all other Subarus with Navi..:)... When I get some spare coin..I will purchase this to see if it works..:)

No reason to spend that much on it, all it's doing is grounding one signal.

soooo cut the signal??? Diode it???? bypass it??? and do we know exactly 'what' signal.. :)


Bill

I'll have to figure that out once I get mine :)

Then once you know the signal it's just a matter of cutting that wire and grounding it somewhere. Sometimes it is as simple as taking a pin out of the harness.

:popcorn: i see good things in the works here :)

Has nobody figured this out yet? The car must be that good that current owners could care less about using the nav screen while driving!

To figure this out, does anyone have an access to this doc: http://techinfo.subaru.com/proxy/676...aviHQFinal.pdf?

Also, review this post from NASIOC:

It could be that BRZ is fitted with Pioneer unit, then to identify it use this code diagram:

P - Panasonic
PE - Pioneer
CX - Clarion
GX - Kenwood
FT - Fujitsu Ten (Eclipse)

US BRZ has the Fujitsu Ten unit in it.

Has anyone figured this out yet? I was just watching an Xvid.AVI file... and the second i put down my ebrake the screen turned blue!!! so sad. I wanna watch inital D while drifting and smoking a cig!

but for 125 I rather put that towards a Nav/dvd that actually works well! This head unit is sooo crappy it makes me sad.

The ebrake one is simply, you literally just ground the wire going to the HU for that.

The NAV I don't think is the ground signal as you don't need to engage the ground to set an address. One of the issues I noticed during my recent trip was I could only find stuff in motion with voice rec or nearby items, and voice rec doesn't let me (in an obvious way anyways) change from "nearby" to "in this city/state". Instead the car has to be stopped and I believe the HU is figuring that out simply from the GPS signal, not the ebrake.

Easy Peasy. Pull the head unit out. Look for the gray plug. One wire is sticking out of it. Cut the wire in the middle. Take the wire that still connects to the connector that plugs in the radio and ground it. Problem solved. Oh, BTW, I grounded it to the ground wire on another connector (the one that has front speakers). Works well.

Any way you or someone else can post a how-to with pics? This would be an awesome mod.

I will pull out the Nav assembly on Tuesday to try and find the ground cable.

Does grounding the ebrake wire allow for phone functions to be used, for example using the dialpad and phonebook?

While Driving I mean...

Writeup!!

Any luck finding the ground? I am hoping to do this mod myself when I find the time...

I actually did not have time, (working 72 hours a week) but I tried doing some test, and I think grounding the e-brake will not accomplish what I want, which is full functions of phone while driving. I think this is GPS based, so as soon as the car gets moving, the phone capabilities are limited, it doesn't matter if the e-brake is engaged.

The ground is on 10-pin power/speaker harness...
12--34
5678910
Pin 7 is Ground.

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.

Good info! Does this allow you to play video from USB while moving?

Yes.

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.

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?

Are full phone functions available while driving shorting the ground like this?

Yes.

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.

Did you take pics? I need them....:thumbup:

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.

Would love to see pics of the whole process.

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.

Ok. THanks for the input. I tried to the pink and didnt work, but nothing bad happened. Thanks for all coming to my rescue LOL...

I will try now to a screw. And report back. I took some pics, will upload later.

Pin 7. I think is black off of ten pin harness.

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.
