Usually it works fine, but some car's factory grounds are pretty shitty.

So if the factory ground is a thick wire I'm ok but if it's a little skinny one I should probably ground it seperately? I've heard it can catch fire if you attach to many ground to 1 wire.

Yes, if you attach too many grounds to 1 wire it can overheat. But the amount of power going through the parking brake and mute wires is next to nothing. It's fine.

will this work on the 90bt also

Yes. Try reading a topic before posting in it.

Works perfect on 90BT

Well, I tried the bypass and it didn't work for me. The only thing I think I may have done wrong is the moving of the one wire. I yanked it out the back of the white connector, and kind of pushed it into the other hole as the directions stated. I wonder if I was able to push it in as far as the other pins. I think maybe it isnt making a good connection.

Is there an easy way to push that little metal pin further into the connector? What methods have those successful with this used?

UPDATE

Works great! that was my issue, didnt have the pin all the way seated

Hi - I did the bypass on the F90BT. I get a warning screen I have to OK before it works. Is this correct? Anyway to get rid of this screen?

Helpful tip for moving the mute wire: Lift the little plastic flap holding the pin with the tip of a knife or small screwdriver. Then you can gently remove the wire and pin connector. When relocating it to the bottom row position 4, turn the pin around (upside down) so that it can properly engage the little plastic flap. Hope this helps!

Sorry, I am new to all this car stereo stuff. I just order my Pioneer AVIC-F90BT with two rear displays. Can someone post instructions with some pictures just to make sure people like me don't screw it up.

Thanks, I can wait to get my unit. Will be attach to a Honda Pilot 08.

Wanna let everyone know that this bypass works GREAT!!!!!! for AVIC-F900BT all functions work did over 3 hours behind the wheel on highways and some city driving. Thanx to all for the info

What about the overall reliability of the unit? Are you experiencing the problems that others are?

Awesome mod, chrisbulla, thanks.

Obviously, for safety reasons, the passenger can safely operate the GPS, etc., for the safety oriented driver. So, when 'another driver' has possession of the vehicle, is it safe to assume that an obscurely located on-off switch on the yellow/black ground mod wire would disable the feature and resume the 'factory' operation?

i wanna do this...but i'm soooo scared...i'm a punk when it comes to messin with anything electrical on my baby(truck)...

anybody in the tampa area wanna help me out?

I tried searching for the answer, so sorry if this is a repeat question. Currently by unit says "parking break is improperly installed....." . It was installed correctly from what I understand (ie. no bypass). My question is for the people who have bypassed their units....does it give the "parking break is improperly.....error?

Thanks for your help....

After pulling everything apart due to no sound with my sirius tuner, all is working perfect now. Must have been a bad crimp?.?

So I can confirm it works on the F90BT

Sorry for the newb question but what is the easiest way to remove the wire from the harness? Does it require a special tool? Dont want to mess up the harness because I pull when I should have pushed.

I used the needle in my "sewing kit" to lift the white plastic tab that prevents the wire from going out when pulling on it.

Then lift it again on the new position to help it go through...

Hope this help...

Thanks. I used a little sunglasses screwdriver. Seem to work fine

I can confirm this does work on the F900BT. No problems at all. Just pay attention and triple check everything before you try it.

i'm attempting this later on this afternoon with a buddy of mine over in Orlando...if i run into any binds...i'm expecting you to be on here HiFiSi or your inbox will be full of PMs!!

No that is hte whole point of the bypass. I actually found it easier to do the bypass then to search through my wires under the dash trying to hook it up properly. Ground two wires and move one wire from a pin to another? I didn't even have to be in my car to do it, which is a lot easier by the way. Doing it in a well lit enviroment and on a desk is a lot easier in cramped car or whatever.

Simply take a small screw driver flat tiped, like to tighten glasses, go to the yellow/black wire, the little white tab needs to be lifted just a bit while you pull the wire, if you do it right it will come right now, now you have to flip it around and push it into the necessary slot.

It's crucial you have it in properly, the very small point goes up, you will know if its upside down because it will be very tough to push in and will stop almost immediately.

When you can see the silver prong match up like the others from the top view you know its in all the way, there was no click type of feel.

Just another FYI: bypass works perfectly on my f90bt

The bypass worked for my F900BT. When I initially had it installed, the guy did the "D3" bypass but it didn't work. I took the car back to him yesterday showing him this page and how the wires were slightly different. Works like a charm now.

Bypass worked great for me. Didn't even give me a warning that the parking brake wasn't attached properly.
