Plug and Play Bypass Kit (DVD, NAV and backup Camera) Discussion

wheee!

This is actually awesome news as now we can wire the hi output (HI setting) from pin 3 to the relay to release the vss signal, and when we switch to the LO setting it will send a 12v signal from pin 2 directly to the reverse signal on pin 81 at the back of the av head. No extra diodes should be required.
What say you Brian?

Yes with a small micro relay we can use this switch.

Regarding the diodes you still want at least one diode so that the 12V doesn't back feed the car when the switch is engaged (remember we are tapping in to the existing wire not cutting it).

Given that the diodes cost cents I would probably also include the second so that when you put the car in reverse it didn't illuminate the button. I would need to double check the rest of the circuit diagram to see if that would actually happen but a diode would solve the problem either way.
