xmx250 Posted March 14, 2007 Report Share Posted March 14, 2007 where is the the thread about "how" the bypass works? not just what to do to make it work, but why does it work? I was interested in reading the responses but i cannot find the thread??? Quote Link to post Share on other sites
sportsfan21 Posted March 14, 2007 Report Share Posted March 14, 2007 I'm not sure there is. However, this is my most logical explanation about the bypass. Not 100% sure if its correct, but it seems pretty logical to me. I'm pretty sure that the bypass disables the unit from using the GPS antenna and gyro sensors to detect whether or not the car is moving. Usually the AVIC will first check the parking brake wire to see whether or not that is grounded. If it is, then at around 15-20 mph its internal gyros notice its moving and correspond that with the GPS antenna. It will then lock the unit. The bypass stops it after the unit sees the parking brake wire is grounded. Quote Link to post Share on other sites
xmx250 Posted March 14, 2007 Author Report Share Posted March 14, 2007 i see where your coming from. i wonder if thats right. Quote Link to post Share on other sites
asianman35 Posted March 14, 2007 Report Share Posted March 14, 2007 personally i think pioneer makes it easy to bypass the unit on purpose because they realize that alotta people wouldnt buy it if they couldnt bypass it, so basically all they do is say if this pin (the mute wire put in the other hole) is grounded allow dvds to be played, navigation functions to work, ect.

MisFit Posted March 15, 2007 Report Share Posted March 15, 2007 if sportsfan were right, then your navi wouldnt work too well once you did the bypass. i think the bypass is actually a way for pioneer techs to have full control when testing and repairing units. we just use it for our own amusement Quote Link to post Share on other sites

And what I'm saying is not that the unit ignores the gyros and sat antenna, I'm saying it just doesn't use those two to determine whether or not to lock out the unit.

cntrylvr79 Posted March 15, 2007 Report Share Posted March 15, 2007 That's strange I remember replying to the original post that asked the exact same question. Weird. Quote Link to post Share on other sites

cntrylvr79 Posted March 15, 2007 Report Share Posted March 15, 2007 like theres never been duplicate questions on here before Na never, not even one. Hell if you dleted all the dupe questions, the total posts in this forum would probably get cut in half or more Quote Link to post Share on other sites
cntrylvr79 Posted March 15, 2007 Report Share Posted March 15, 2007 Ahh found it. Page 4 towards the bottom and continued to page 5. http://avic411.com/forum/viewtopic.php? ... ht=parking Quote Link to post Share on other sites
Itchy Posted March 15, 2007 Report Share Posted March 15, 2007 I think it all comes down to liability. If you get into an accident because you were entering an address while driving, that opens up a door for a lawsuit against Pioneer. However if you knowingly and unmistakenly alter the device to override the safety measures implemented by Pioneer, then you exonerate them. And in the Dx case, it'd be tough to prove you accidentally removed the mute wire, put it in the other hole, then grounded it along with the parking brake. Alpine takes it a step further by making you use the foot brake and parking brake in a particular sequence - hence the electronic bypass. Last time I checked, all the kenwoods needed was a ground connection for the parking brake. Quote Link to post Share on other sites

dropped.jag Posted March 27, 2007 Report Share Posted March 27, 2007 what if the slot that the mut wire is in actully controls the mute funcition and the gyro.so if you move it into another slot it shuts off both functions?is that plausable? Quote Link to post Share on other sites
sportsfan21 Posted March 27, 2007 Report Share Posted March 27, 2007 damn, i cant believe jason allowed that sn! Wow I didn't notice that the first time around. That def shouldn't be allowed. Quote Link to post Share on other sites
