AV In On A Fujitsu Head Unit? ... YES

[ScubaDooba]

All,

I've been mucking around with the head unit (PZQ60-00535) in my '13 SR5 in an effort to enable the auxiliary port's video in capability. After reading plenty of other sites, and a bit of trial and error, I have finally had some success and managed to get movies playing on the screen from external devices (currently only my iPad and iPhone, but will be investing in a TV tuner in the near future too).

Here's just a couple of quick pics to show it off ... I will write up a "how to" in the next day or so and post it when finished.

*** EDITED TO CORRECT RESTOR VALUES ***

Ok, here’s the details on how to enable video in on the Fujitsu Ten PZQ60-00535 so as to watch videos from external sources such as a DVD player, TV tuner, iPad, iPod, etc. I hope this all makes sense.

Technical Stuff

Start with Auxiliary loom – part number PZQ60-00190 -


Locate resistor on loom –


Change resistor value from the original 1.6KΩ to between 0.5k and 0.65k either using a single resistor or running a 1.0K resistor in parallel with existing (other forums make mention of changing resistance to 1.0K however I found this did not work on my unit).
Photo shows 2 x 1.0K as I “lost” the original 1.6K resistor when I was mucking around with the cable. Thinking the 1.6K and 1.0K worked when combined, I then got somewhat "resistance-challenged" (until set straight by others below !) and confused the values not thinking they were in parallel and hence 2.6KΩ so when I installed a single 2.7K (closest I could find to 2.6K) the mod does NOT work ... when the cable is then connected, AUX audio only is available.


Pin up an RCA socket with pins to suit the 28-pin header -


Plug cable into pins 13 & 14 of the 28-pin header -




Add Audio RCA sockets too – this makes it easier to tap in your AV device behind the dash, rather than having video running behind, and audio into the aux port on the front -


Plug this cable directly into rear of head unit … camera loom can plug into this one with the vehicle plug hooking into it. This is essential, as there are no throughput wires for aux (video or audio) from one plug to the next on any of the supplemental harnesses -


Check everything before re-fitting the head unit and if all is good, bolt her back in.

Screens

You should notice the old AUX IN button has had a name change to AV IN.


When you touch this button, you should see the following screen -

Selecting Apect -


Back out/return to preivous screen -


Play a video from a device and enjoy (just touch the picture to bring it up full screen) -

Nice work.

Nice one!

Only thing is the two 1K Ohm resistors you have soldered in are in parallel so they actually equal 500 Ohm.

When you tried the original 1.6K Ohm and a 1 K Ohm it would have equalled 615 Ohm, which you said also worked.

So I would say we should be aiming for a 500-600 single resistor

[ScubaDooba]

Thanks, Aandy, I must admit to no real knowledge of resistors, polarity and the like, so yeah you are right, my numbers are way out ! On other forums, people make mention of needing 1k to turn video on. Could be why a single 1k resistor didn't seem to do the job for me as I may have had it the wrong way around ?

[Steveyb]

They are not polarity sensitive

Req = 1/{(1/R1)+(1/R2)+(1/R3)..+(1/Rn)}
Series is Rt = r1+r2+r3

Your total resistance in parallel will be less than the lowest value resistor in the circuit

Easier calculation: Find the RT (Resistance total) in parral = (R1xR2) / (R1+R2)

in this case ( 1.6x1.6 ) = 2.56 / (1.6+1.6) 3.2 = 0.8 ohms

Actually you require 800 ohms

recalculate buddy, a 1.6 and a 1.0 this time. equals 615

Sir you are correct on those figure's based on 1.6/2.6.

I was quoting on the original AV resistance of 2 x 1.6 ohms.

Cheers

[aandy]

There was never a 1.6/2.6

There was never 2 X 1.6

are you just messing with me? its working


Original Resistor = 1.6, AV did NOT work

then he tried 1.6 in parallel with 1.0 which equals 615, AV DOES work

Then he tried 1.0 in parallel with 1.0 which equals 500, AV Does work

He also tried a 2.7 single resistor, it did NOT work.


so we know 500 works also 615 works, these resistance figures are in the range, we know from his testing 1.6 is too much and obviously 2.7 is too.

1.6 with 1.0 = (1.6*1.0) / 2.6 = RT 0.615 ohms hence why i stated (1.6/2.6)
1.0 with 1.0 = (1.0*1.0) / 2 = RT 0.500 ohms (1/2) not messing with you im agreeing with you calc's

sorry for any confusions.

have a nice day

[ScubaDooba]

Well, that got out of hand !!! For my next project, I will make sure I get my calculations right ... now that I know the formula

[William_Foster]

Great write-up ScubaDooba, I'll be interested to see how you go with the TV Tuner

[ScubaDooba]

*** Updated original how-to with corrected resistance values. ***

TV tuner hopefully by end of the week ... just trying to choose between the new HiTV 4-tuner (Pure 4) or the Alpine unit as I still havent yet decided which head unit I will eventually upgrade to ... Alpine INE-W947Ei (tuner integrates into touch screen for all controls) or Eclipse AVN-827GA.

[mattwhite]

I understand all of it except the yellow RCA plug to the 2 pins. Where do you get the cable and the pins separately? Jaycar?

[ScubaDooba]

The yellow plug just came from an old A/V cable I had laying around. The pins, or rather sockets, were a bit harder to get.

I had an aftermarket cable that I didn't need, which came with my Carbon Car Systems rear camera. I liberated two pins from the 28-pin plug on that harness, and to turn the pin into a socket that fitted perfectly just cut the pointy bits off the end !!! The way the ends look, they seem like a pin and socket in one.

[William_Foster]

Any update on the TV tuner ScubaDooba?

[ScubaDooba]

Hi William,

I ended up with the Alpine tuner (although IMO the new HiTV quad tuner is better) as I now have an Alpine head unit in the vehicle and the two are compatible with the touch interface, but before I switched, I tried an onld tuner I had with the Fujitsu and everything worked ok (less picture quality due to crap antennas tho).

Found out after purchasing the Alpine tuner that the integration is only minimal so still have to use a remote control, and if I had my time over again I would have gone for the HiTV. Both are the same price but with 4 tuners the HiTV is way superior.

thanks for the info.. which model HiTV would you recommend
