Just got my car today. had the head unit professionally installed.... I think the installer cut corners or something. He didn't ground the parking brake wire so everytime I turn the car on I get an error to ground the wire, but I just hit OK and it carries on as normal....

Anyway, I cannot access the system settings or Navi settings in the unit at all. I'm not sure how to what to do?? Does the grounding wire play any part in changing the settings? The AV Settings and AV Sound is accessible but that is all...

Help me please. Thanks

There has to be 1 of 2 things done before you will be allowed access to those features.

1- If the unit is hooked up as directed in the installation manual, the parking brake wire will be hooked up to the parking brake switch on your car, and the car needs to have the parking brake engaged and the can not be moving before it will allow access.

2- Perform the bypass as per 1 of the 4 stickied topics here and you will be allowed to use those functions at any time you want even while the vehicle is in motion.

That's what I thought. So it is the parking brake wire being disconnected that won't allow me access to anything.

I can't even program in waypoints and such in to the GPS. All I can do is watch an arrow move along a road without a destination.

I'm gonna tear that installation guy a new one.

Thanks, bud.

Hey, i just installed this unit and having the same exact problem..

The link you posted there to the forum for D3 hacks. Does that applies to the F700Bt as well?

All i have done is performed the MUTE wire relocation per the hack forum for F-Series, which move it to a different location than the Avic-D3.

Can i do the software bypass?

The bypass for the F-Series can be found in the F-Series Hacks/Mods forum, it's a sticky at the top.

You can perform the software bypass or the mute wire relocation bypass, but in both cases, the parking brake wire needs to be grounded.

What do u mean by "Grounded"?

I check the installation manual and it said to tap the light green brake wire to the "positive" line of the brake line and DID NOT mention anything about the ground wire or grounded??

Can you please help me clear that up? Should i follow the manual and tap to the power wire or the ground wire so it can be "grounded" like everyone here refer to?

Thanks a lot.

Also, what does the Yellow Mute wire connect to? I have done the relocation for it but it doesn't connect to anywhere on the other end? good or bad?

Do you have to connect the cable to the parking brake and ground it or can you just ground the parking brake cable on the unit directly without hooking it up to the real parking brake.

I'll answer the last two posts in one go.

To have access to the settings and phone screens, or for either the software or hardware bypass to work, the parking brake lead in the wiring harness must be connected to a ground.

That can be a constant ground (by connecting it to the ground lead in the harness, or other suitable grounding point), or it can be a variable ground (like the parking brake circuit).

Pioneer, understandably, wants you to connect it to your cars parking brake ground so that the above functions will only be available when the parking brake is engaged. That doesn't make very much sense on a bypassed unit (why would bypass it in the first place if we're just going to rely on the parking brake to be engaged), so just connect that lead to the black ground wire in the main harness (along with the relocated mute pin if you choose to do the hardware bypass) and you're done.

Does that help?

YES!! Thanks so much. You just save me a lot of time because its super hard to get to the e-brake location on my car.

I will tap that line to the ground line on the main harness.

Thank you so much

Yeah... sorry. I put the wrong link in there. My bad.

skicrave awesome! You have made me so happy.

I'm installing my kit tonight and the though of accessing the parking break cable in my car is scary. So that's freaking awesome news for me!

just ground it to a vehicle chassis through a screw when installing the unit. i have three wires hooked up to ground. don't remember what they all were though...

its not like when I touch the Settings Icon and see all the options like ''calibration; screen adjustice etc''... I wanted to play a CD but I just cant go to this option.. Why is the AV SOURE untouchable?? when i touch the other options like Phone/ Nav. i hear sounds , but I cant access the AV menu to choose to play CD or radio for example?? I've put a CD , too but nothing happened
