No problem...glad it worked.

Thank you guys, this helped me very much.

I have the HD3 and you dont need to change the place of the Mute wire, theres alredy a remote wire on that slot, perfekt:)!

looks great in my Celica T Sport.

Thanks again guys(girls?!)

Best regards

First of all, this forum rocks - thank you all for contributing!

I recently installed an AVIC D3 in my 2006 Golf TDI GLS - I used GomobileR32's DIY over on VWvortex to find all the correct wires. All wires to the Metra harness, VSS, night mode & body ground were stripped, twisted, soldered, liquid electrical taped, electrical taped (after the liquid stuff dried for at least 2 hours) and bundled with cable ties.

Yes, this took quite a while.

I did the bypass mod. I confirmed the moved mute wire, ground & parking brake wire were connected, grounded through the harness as well as grounded to a ground point on the power distribution block. In fact, I've checked this about 20x at this point. With a multimeter. A good one.

The bypass works - we can view DVDs while the vehicle is in motion. On the instrument/connector screen, the parking brake is marked as being on. However, I don't have the ability to input an address in the navigation section. POIs, address book, address entry, etc - all greyed out, all the time. Parked, moving, eluding the police, doesn't matter. They're unusable.

Everything else works fine. The map is working beautifully, the VSS is operating correctly, all the internal gyros respond well. I'm stumped!

Any ideas?

I've read that Pioneer may be disabling the mute wire bypass "in the future". This is a 2007 June built unit. The bypass works (Office Space looked pretty decent and the sound was excellent) but address input no go.

I've left the grounded mute wire out of the white harness, and that makes no difference. Also switched the mute wire with another unused wire (remote control?), grounded it and had no luck.

The only thing I can think of is that I'm using a copy of my navigation discs, but Nero didn't complain a bit and burned the DVD+R DL discs without a hitch. So, off to try the real ones.

And yes, I've checked all the wiring. Really, I have. Multiple times. Using a Fluke 76II true RMS meter. The mute wire is hooked up correctly, making contact with the pin and is grounded. And so are the parking brake & ground wires.

Thanks again!

The real ones worked! It works!

Man, this unit is incredible. Thanks for the help in documentation to everyone, and let it be known that using a Nero "Disc Copy" on Memorex DVD+R DL caused me to not have full nav functionality. Hopefully nobody else will have this problem.

First, I want to say thank you to all of you and this forum. These information are very helpful.

Does anyone known where the VSS wire locate? on the HONDA CRV 05.

Please help if you known.

Thank you.

i did the bypass and everything works, except my navi is all screwed up now. my vehicle dynamics says its not available except like volts and direction. and also my pointer that represents my car on the map is now off the road and turned another direction than my car actually is, what could be wrong?

Sorry to be such an idiot...How do you ground the yellow/black wire and green wire once you change the pin location?

you can use wire nuts, snap connectors, solder and tape, doesn't matter as long as it's grounded.

is the bypass supposed to let you play with the navi?? becuase i did it and my d3 lets me play with the ipod while driving but when typing info into the navi the info turns dark grey and doesnt press until i stop at a red light

Look 5 posts up....sounds like the same issue...

Assuming all your connections are good?

i just called my guy, he siad that he moved the mute, then grounded the mute, and grounded the park brake wire

maybe because as the other guy was saying its becasue its a 2007, then again the cds are the real ones, not fakes

You need to check all the wiring to make sure it was done properly. If it doesn't work until you physically stop, he either didn't ground the correct wires or didn't move the mute wire.

ill go to his shop and ask him to open it up, thanks

After reading through pages and pages of conversations and multiple threads on the topic, I decided to filter out the duplicates and condense all important information into a single post. This has helped me and hopefully others will benefit from this in the future. Thanks to all the original posters for the content, especially 'necro' for his fantastic tutorial. Again, this is just rehash from others experiences with the bypass, nothing new;

Bypass instructions

Step 1: First remove the MUTE wire (yellow/black) with a pick

Step 2: Insert the MUTE wire into the empty slot right above the MUTE wire

Step 3: Ground the newly moved MUTE wire separately

Step 4: Ground the PARKING BRAKE (Avic-D3) wire (light green) separately

Location of MUTE wire and PARKING BRAKE wire

- There are two harnesses...one has all the power/speaker wires/parking brake/vss/etc...black plug which connects to the D3...

- The other has a white plug...and has the RCAs and mute wire on it...that is the one where you need to move the mute wire to the pin above it...

Important !

- Do not confuse the Avic-D3s parking brake wire with the vehicles original parking brake wire.

- The cars original parking brake wire remains untouched.

- The Avic-D3s parking brake wire (light green, on the harness with the black plug) gets grounded

Grounding instructions

- You could put a wire tap on the GROUND wire (black) and ground the PARKING BRAKE and MUTE wires to this.

- You can use the wire tap that is already on the PARKING BRAKE wire to tap into the GROUND wire. You could also use a tap to connect the MUTE wire to the black ground wire.

- Use t-taps, butt connectors or similar for the wire tap. Better to ground them (well secured) all together at one point. The more connections you have, the more the chance that something will go loose, so reduce the amount of individual ground connections

Best way to remove the MUTE wire and how to properly connect it to the new location

1. Do not rip it out. Use a small eyeglass screw driver or something and poke the metal tab sticking up. That tab on the crimp is what is keeping it in. Poke that down and it should be pretty easy to pull out that wire. Again. DO NOT forcefully pull out the MUTE wire from the harness.

2. The pin on the mute wire has a flat side and a side that has a gap in it. The gap goes on the inside and the flat side goes towards the outside (where the plastic clip is). Push the mute wire in all the way, then try and pull it out gently. If it comes out, it's not in all the way.

3. Make sure the MUTE wire is rotated 180 degree before putting it in the new position. Rotating the wire will make the lock pin line up with the lock tab. If it is not locked in it could get pushed out when you plug in the connector or make poor contact.

Tips to avoid bypass cut-offs

1. Use U shaped terminator connectors or better to secure GND/ground connection (as opposed to bare wire)

2. Make sure you do not bend the pin crimped to the MUTE wire during the move operation.

3. Release the plastic clip holding the MUTE wire in instead of yanking the wire from the plug.

4. Make sure that the ground connections are really good and secure

How to test the bypass is successful

1. Drive it past 15mph and see if it will play video.

2. Check if DVD playback works @ 60MPH

3. See if you have the ability to enter new destinations using address search

4. Also, you should never get a warning about your parking brake being connected incorrectly ("improper parking brake" message goes away)

5. If all connections are done properly and the bypass does not work, then try rebooting the unit using the hard RESET button

6. When you go into Hardware Info screen, then Connection Status screen, the parking brake should show ON

What about the VSS (Vehical Speed Sensor) wire?

- The VSS wire should be connected as instructed in the manual.

- The VSS wire has functions independently of the bypass and is should be connected for accurate navi performance.

I know this is a dumb question, but I can't find anything for the AVH-P4900 ANYWHERE.

I think they have done something to prevent the bypass now, or at least made it a little harder to bypass. I know all of my connections are correct. I have done the bypass many times, working for a car electronics company, yet I just recieved my own brand new 07 unit and it is not bypassing. It works fine until I start driving. When the unit senses im driving it says the parking brake is improperly connected and grey's out the address search feature, and video.

I just had mine installed yesterday and it worked

I work for a pioneer dealer, and got one shipped directly to me from Pioneer. I think it may just be the newest units coming out are having this problem, I have read through some posts and it sounds like im not the only one having this problem. Believe me I installed one last week into an FJ Cruiser and the bypass worked fine.

It will have a date on the box. My new one was date July 07

Mine says august of 2007. Dont know... Im confused.

OK... Sorry for the false alarm. But the one task I gave my brother of moving the mute wire ended up being the culprit. He didnt have the pin ALL the way in the hole. Anyway, all is well! And Bypassed! Thanks guys!

my aug 07 model works fine

First off, this board is mad helpful. However, I have a question.

Just bought a d3 and plan on installing it this weekend, already changed the mute wire. I was wondering if you guys popped that red cap off of the parking brake wire to ground it. I've read through a few pages and have not seen that in particular answered. Thanks.

Just wanted to say this forum was very helpful. I bought this system and planned on putting it in myself. I had no idea what I was doing do to the fact I have never done anything like this before. I know have the unit installed, with the ipod connector and everything works perfect. Also I have the bypass working and had no problems setting it up and I still have had no problems. I do not have the reverse signal nor the vehicle signal hooked up. Great product!!!
