OnStar has nothing to do with the bypass - except that the Mute wire, which is normally moved to do the bypass, might already be used by OnStar. That would be a problem - only because you need some compatible wire to insert into the "bypass" position in the harness. The Mute wire is the common choice - only because it is normally not used. You'll need another wire to insert instead. Sorry, I can't help with Onstar, never touched one.

well i had the audio shop put everything in and they didnt use the mute wire and i did the bypass and it works hope everything else works but i dont use onstar let me know if anyone else has done one with on star and thanks for the info and help RonS

will this work on an avic z140?

Just letting you guys know,the bypass worked from the z130

I did this and functions are still greyed out when driving. Is there something I'm not doing correctly?

You did it wrong or you have a bad connection.

Confirmed for the Z140!!

I had a shop do the bypass for me. I guess they didn't do it right.

One more in the confirm department for Z140 - works like a charm.

Same thing with my bypass as Alky181. I did exactly what the Youytube video showed. As soon as I start driving, the ADDRESS touch command goes gray. All is fine when stopped and in gear with P-brake off. However, I do get the message about the P-brake being disconnected.

My unit was already installed by a shop that said they were liable if they did the mod, so I had to do it. The P-brake (light green) wire was already connnected up. I just cut the wire and connected like the vid and left the end running to the P-brake connected.I am thinking that I need to connect that cut lead as well to the ground.

Any thoughts?

This statement shows that you should not be doing anything install related in your car.

Nice advice there "bro"...how about a solution rather than a stupid ass comment. This is supposed to be a helpful forum genuis. I suspect this isn't the first time you got grilled for this kind of posting.

I'm having a similar problem. Avic z140bh already installed professionally. I've grounded the green wire and moved the mute pin up just like in the video etc and grounded. Functions still shut off when driving. Any thought?

If i am using and ms-frd1 harness ( to retain my ford sync) will that mean I cant use the jute wire since I need that for sync? Anyone try this?

MicroBypass has extra pins for sale with instructions if you don't want to remove the mute wire. I was using mine for onstar, so I needed a pin too. They have the oem pins from Japan.

this is the exact thread i need.

i'm having problems similar to the last few guys. ford f150 w/ sync, ms-frd1 harness, and the pioneer Z140. used an extra wire for the parking brake bypass. tested it out before assembling the rest of the dash and it worked great. could use full nav functions while driving. then i used the mute wire for the sync and tested it out and LOST the parking brake bypass. why? am i doing something wrong? do i need an extra pin because i am now using BOTH the mute wire AND the extra / unoccupied slot?

someone help me out here. thanks!!

UPDATE:

i pulled the unit back out to see what the deal was. turns out everything was connected (mostly) property; the right wires were connected; wires were grounded appropriately; BUT, the bypass wire had slipped ever-so-slightly from its seat in the pioneer harness and no longer had a good connection. so i pushed it back in, made sure the plastic stop in the harness was in the full lock/down position, and TaDah! it works like a champ now!

good info in this forum. thanks guys!

Check Out the Microbypass.com Website they sell the replacement Pins. there the same for the Avic X & Z. Ive been using them I go thru about 10 every 2 weeks.

Ok this might be off topic, I did the bypass on my z130bt it works great. Wondering though if I can put a switch on the ground wire so I shut the bypass off so it won't work if questioned about it if "someone asks".

Yeah this question gets really old. You can but there is no reason to do this. Its not illegal anywhere to have the bypass. Its illegal to watch video. The two are totally different.

And that's why "someone might ask" if i was and want to show i wasn't

vblue is right. these are two different things.

so lets say they pull you over.

and if they caught you because they saw you use it, its pretty a done deal. you got the ticket. they would not pull you over if they didnt see you do it in the first place. kind of like they asking you how fast you were speeding? if they pulled you over for speeding your done... its basically a rhetorical question at that point.

now if they pulled you over for something else and ask you if a video is playing while you drove, then you basically say no you were not watching anything. only you can screw yourself by admission during the traffic stop by the officier. plus they can NOT physically go into your car and turn it on. you also do not need to show if it does or does not do it as they never saw it happen before the traffic stop.

Hi guys,

I have an avic f40bt which looks pretty much the same z130/z140. I installed mine awhile back ago and just grounded the hand brake. Everything seems to work, as far as i can tell. I am able to ise the GPS and have video playing.

Only recently i joined this site and i've noticed you guys re-pin this wire and ground it. Why is that?
