Does anyone have a confirmed bypass method for the Non-AVIC units?

You need the micro bypass relay or a Double pulse relay switch.

This is correct. Used the micro bypass for mine. Very simple install.

I just used a normally closed push button hidden under the dash.  Simple tap when I need it.  Most of the time I don't.

I used this one from Radio Shack

This would work also. push button, switch, NOS button

Thanks.  I used the same bypass and it worked.  Install was very simple.

just order a micro bypass you wont even have to think about it again

I put the micro bypass in on a permanent basis when I installed the 4000.  No problems.

I installed mine yesterday and I am having problems with the bypass relay working intermittently. (avh 4000nex head unit, 2007 infiniti g35 coupe with bose, pac roem nis2 harness).

For some reason when i play video off a usb stick it works the first time (gives me the warning message and then I can press OK and watch the video) but then if I turn the ignition off and try again to watch video it gives the warning message again and I am not able to tap the OK button because it is greyed out and it only plays the audio. Strangely, if I turn the unit off and switch the usb key to the other usb port then I am able to watch the video again but if I turn the car on and off the same thing happens again.

Any ideas? How did you wire yours to get it to work?
