Hi dudes, I have just finished installing a JVC KW-AVX700 unit into my R32. JVC have built in a "feature" that won't allow a viewable playback unless the handbrake is applied. However, it is also stated that the warning won't appear unless the handbrake and JVC unit are physically wired up to eachother.

The instructions say the following:

"If the parking brake is not engaged, "Parking Brake" appears on the monitor, and no playback picture will be shown. This warning appears only when the parking brake wire is connected to the parking brake system built in the car."

The funny thing is that I didn't hook the wire to the handbrake so the warning should be disabled. Furthermore, I am still getting the warning even when I do apply the handbrake.

Any ideas? It would be sh*t to have an incar DVD if you can only watch it when the car is completely stationary....

your park brake sensor on the unit should be looking for a negative signal.

Just ground that wire from the head unit to a good source of negative ( chasis) and you should be fine.

righto... i earthed the park brake wire and now it's fine... thanks all for your help...

..phew!!

i know.... i knew there had to be a way around it... just glad it was so simple... imagine having the unit without being able to have the video clips running while your driving... or going for a trip with your mates and telling them they could only watch the display at the traffic lights... pfft...

thn imageing being distracted by the same uint and running over a pedestrian. thats the reason it is there :P

LOL i know its not funny but this guy got the sack from JB-HiFi for not connecting it to the park brake signal... we use to make customers sign an document if they wanted it done with the wire striaght to negative, it said something like "we are connecting this to the park brake signal wtf you do with it after is your business" something like that to keep us from getting sued in an "unlikely" event just like Chris stated...

If it is an indash monitor you might want to hook up a switch somewhere so the PoPo cant get you for it too.

bit of an overkill don't you think....? just risk it and turn it on to radio if you get pulled over... fairdinkum...

ive got a miriad of switches i call 'cop switches' that i just bang to the up position when i go past cops... saved me a few times...

the best thing to do is to get a two phase switch and ground one end, and send the other to the hand brake so if you ever do get shit about it, just flick the switch to handbrake mode... sup to you though...

got a diagram to show me...? Do i still ground the handbrake wire from the back of the HU or do i rig it up properly to the handbrake then use the switch to ground it while the handbrake is off??

that diagram took me 2 hours, so i hope you appreciate it!

go to jaycar, DONT SHOW THEM THAT, they will laugh at you, tell them what you wanna do and what kind of switch you need, then wire the ground from the head unit to the single input, then ground one of the outputs, and wire the other to the ground cable on the handbrake...

finding a suitable place for the switch is always fun... i got 5 wittle ones in my drink holder :ninja:

I just realised that I didnt even attach the hand brake wire to anything.. and it plays as normal... what the..?

But the only problem is, that there's no power running to it when the car's turned off. Therefore.. the clock resets, and the CD/DVD starts from the begining..what the?

you've got your 12V+ and your acc wires mixed up... when you turn your car off, it kills the 12V+ line that should always be on, and uses the ACC line as battery backup, which is obviously off now...

take it out, swap em over and you should be fine...

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
