Last night I decided to modify my MFD in my GTR.

I can flick the momentary switch and force it into tv mode. Problem is I keep getting to the black screen with yellow japanese comming across the middle of the screen.

I have the link soldered in aswell, that according to the tutorial will eliminate this message.

Anyone run into the same trouble and can give me a heads up on the problem.

One of the components was completely missing on the PCB board. Since Im not using the factory sat nav head unit, I stole the suface mount resistor off that and it all worked. It was the one above where the link is soldered in. Soon as i put that in I had signal no worries, so i now have a reverse camera in the gtr.

its a variation on the MFD mod posted here. you can select the 'tv' and with that selected you have the choice of reverse cam or in that case garmin navi. camera takes over when reverse is selected.

Sorry OP to hijack this thread, but here's nearly as good a place as any.

Chris - have you played around with touchscreen overlays on an MFD? I've been pondering using my MFD 'tv' button to display output from my CarPC GPS (it has the ability to do that with the second display). The drama there is that it would then really need a touchscreen overlay to be useful.

My concern with one of these would be that I have a sneaking suspicion that it would break the 'sunlight readability' of the MFD screen. The last thing I want is to lose is that. It's so nice having a clear screen even in the brightest conditions.

Any feedback or experience you have would be great.

depends. if you are using the '$5' ebay ones - yes it does affect view. there are companies that do the newer capacitive ones that work fine. size will be the issue though. that is a odd sized screen.

I looked at it a while back when I was doing a few GTRs and the idea was to pop a overlay on the GTR screen and drive the garmin with it. had trouble finding something to fit.

does it need to be in tv mode for the auto switch to reverse cam or can it be in normal "gauge" mode and will auto switch to reverse cam when reverse is selected?

the one I pictured above was set up using the TV button first to get an alternate image and from there the camera took over as required.

I can knock a circuit together that will switch it over whne you throw reverse and switch it back in forward gear.

as for cost probably best to ask someone down your way. I can tell you that if I did it here $600 would not be out of the question by the time I sat down and designed a proper PIC based switching circuit for it,supplied a decent camera and fitted it all.

      R34 Skyline climate control unit transistor

      That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      Blue slip

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
