I am brand new to this site. Hey all! I just replaced my eclipse head unit with avic z140bt. Th einstaller helped me a little and installed a toggle switch to eliminate the e brake issue. I was so used to the eclipse, just touch while going, no matter what. Now this z10bt is being alittle stubborn. Even with the switch, when I hit 10 mph, it shuts down all acess to the things I want on! I have read the hacks and have concluded that now I am really confused on what the BEST way to do this is. I don't want to harm the unit or lock it up, but I want everything useable while cruising. Please help.

Your installer is not very competent. To find the correct method of bypassing the Z140 (same as Z130), go to You Tube and search for Z130. You'll find several videos.

Look over the threads in the Z1xx forums. The bypass is well documented and works for all units in this series.

Reading over the forums, it is hard to tell which bypass is the correct way to go. Do I add the green wire and just ground it only to find that it works for a short period of time or remove the yellow wire and plug it in to the unused hole on the other connector? Which is the right way to make sure I don't screw anything up? Or do I add the relay? Has anyone locked up the unit or fried something or had something not work because of this?

There is only one way detailed in the Z1XX forums and only one way to achieve the bypass.

Ok, so it's the same as the 130bt? I didn't find anything for 140bt specific. Link?

Sorry, it is a z140BH.

They are all the same for the Z1XX series. So yes, its the same.

Ok, I think I have done it correctly. There is a sreen option under the settings that now shows the parking brake as being on all the time. I will try it and see what happens. Thanks for all your help! I will post back with results.

Went for drive today and it works great. Thanks again for all the help. Now I have to figure out how to get the I touch to stay connected when I turn off the truck ad start it again. It sees the Ipod, but doesn't play until I unplug the aux wire and plug it back in again?

What aux wire? What cable are you using?

Those of you that have successfully done the bypass on a Z140BH, do you still get a message about the parking brake not being connected properly, and then having to hit the "OK" button to bypass the message???

No message. I am using the cable that came with the head unit and my own ipod to usb cable and the 3.5mm aux wire.

The bypass is not done correctly.

That's not the way to interface with the iPod. You need a CD-IU51V cable. It has USB and 3.5 on one end and an Apple 30pin connector on the other. It does not use the aux (headset) output jack on the iPod.

Damn, I'm guessing the tab on the wire I took from an older Pioneer harness isn't long enough to make contact with the pin on the Head Unit connector. I guess I will have to purchase the correct cable online since I don't want to use the Mute wire.

Make sure the pin is properly seated in the slot. That is almost always the problem with symptoms like yours.

I was pretty sure I seated the cable as far in as it could be when I first did the mod this past Sunday, but I will double check it later on today. Anyway, I went ahead and purchased the cable from MicroBypass because I just have a feeling that is what's causing it.

Thanks for your time.

Thanks Ron. I realized this when I actually read the manual. I ordered the CD-IU51V cable from Amazon last night.

Ordering from Amazon will likely be a problem. Many of those cables are knock offs and wont work.

I hope not. But if it is bad, I will send it back and order one from someone else. The cost is the same, about $42. Just free shipping from Amazon.

Received my CD-IU51V cable from Amazon yesterday. It is a red tagged authentic Pioneer Corporation cable. Will see if it works today.The cable itself has an orange tag on it <CRW1549-A> Three rings with tip. Hopefully it will work without having to unplug/plug in everytime I start my truck.

I was correct. The connector on the wire I took from the spare harness I had lying around was too short. It just simply wasn't reaching the pin in the stereo connector slot (it was about 1/3 of the length it was supposed to be). It's working beautifully now

Look at the attached picture and you will see the difference in the connector lengths.

Just an update. I installed the new CD-IU51V cable from Amazon and it works great! Thanks for all the help on this forum. I just wish the pioner was as user friendly as the Eclipse unit I have. So many buttons to push just to do one thing. Maybe over time I will have it figured out.
