spaceywilly Posted March 31, 2009 Report Share Posted March 31, 2009 Yeah this is incredibly easy and worked great. The secret for getting the mute wire out is to push down where you can see the metal clip through the holes in the white plastic part, then it will just slide right out. I used a really small jewlers screwdriver to do it. Should've taken a picture... Quote Link to post Share on other sites
fordguy Posted April 4, 2009 Report Share Posted April 4, 2009 I did the bypass last night and all seems to be working good. I must say it was a major pain trying to get the yellow wire into it's new home. After several attempts it finally worked. I was nervous for a minute though. Quote Link to post Share on other sites
redpit10 Posted April 7, 2009 Report Share Posted April 7, 2009 Registered on this site just to say thanks to the OP. Plus I found a real easy way to take out the mute wire. Just take a sewing pin and you can just un-clip the wire by gently prying the little tab up ever so slightly(on the top of the harness where you can see into the harness). Literally took me about 5 seconds to take out, and slid right in and locked into its new home right in about the same amount of time. The key is the sewing needle/pin.

spaceywilly Posted April 8, 2009 Report Share Posted April 8, 2009 Hallo, new here with F900BT and can somebody explain me what makes only break wire grounded and what makes only moved mute wire grounded?  Thanks Janekx  What do you mean? Both wires should be grounded. Quote Link to post Share on other sites
janekx Posted April 8, 2009 Report Share Posted April 8, 2009 I know but why? what that pin 4 really do Quote Link to post Share on other sites
NewRSX02 Posted April 9, 2009 Report Share Posted April 9, 2009 Hey guys, I just recently bought my F900BT. Can anyone confirm whether the hardware bypass will work on a 2.0 firmware AVIC-F900BT? I heard of stories where only the software bypass works with the 2.0 firmware update. Quote Link to post Share on other sites
NewRSX02 Posted April 9, 2009 Report Share Posted April 9, 2009 Bump! Someone please verify this for me! Quote Link to post Share on other sites
minifreezer Posted April 9, 2009 Report Share Posted April 9, 2009 Wire bypass works with firmware 2.0 verified. Quote Link to post Share on other sites
NewRSX02 Posted April 9, 2009 Report Share Posted April 9, 2009 Thanks minifreezer. The only reason I'm so skeptical is because I have a buddy who works at Future Shop and does car audio installation and when he tried to do the bypass for someone using the hardware bypass, it worked for a few days and then stopped working for some reason. And he says he triple checked all the connections and that they were soldered so I can't understand why it wouldn't work for him. His friend's using the 2.0 firmware too. Any ideas why it may not have worked? Quote Link to post Share on other sites
mmathai77 Posted April 9, 2009 Report Share Posted April 9, 2009 yea it definatly works, i just did it on a 2000 BMW 528i. I hooked up my Avic F700bt to it, works like a beauty. Its a 2.0 also! easy as hell to do this hardwire bypass, i just grounded mute wire, and brake wire to the radio ground along with the harness! Quote Link to post Share on other sites
janekx Posted April 10, 2009 Report Share Posted April 10, 2009 Looks like that nobody really dont know why pin 4 grounded and looks it that it is widely know turkey Quote Link to post Share on other sites
spaceywilly Posted April 10, 2009 Report Share Posted April 10, 2009 The parking brake wire usually sends an on/off signal from the parking brake to the Head Unit. By grounding it you are telling the unit that the parking brake is always off. If you don't ground this wire you get an error saying the unit is wired incorrectly. Â The other pin (the one that we are using the MUTE wire to ground) is a safety bypass signal. Grounding this signal is what actualy bypasses the parking brake safety measures so you can use the unit while in motion. At least that is my understanding. Quote Link to post Share on other sites
