Ravage Posted October 19, 2008 Report Share Posted October 19, 2008 I'm looking at the install guide for the avic f70bt and I want to know about a couple of the cables. PINK: Car speed signal input cable What happens if I don't connect this cable? Is it ok to leave it disconnected? LIGHT GREEN: Parking brake on/off Same question, what happens if I don't connect this cable? Also I am going to order the mitra wire harness, but it doesn't look like it has a dimming cable? Is it there? http://www.crutchfield.com/App/Product/ ... =120707552 I don't have the harness yet, but from what I know it should be an orange or orange white cable, but there are no orange cables on that wire harness.

Flipper Posted October 19, 2008 Report Share Posted October 19, 2008 Go read this... http://avic411.com/forum/viewtopic.php?t=17013 The wire harness should have wiring instructions with it as far as the dimmer etc I think the VSS (speed wire) can be left unconnected but you should connect it. Looks like you have a nissan, double check the proper/best way to hook up the speaker wiring. You may have better luck getting info on that by looking on some nissan forums. Use the search function on this site for more info. Most of your questions are probably already answered. Quote Link to post Share on other sites
Ravage Posted October 19, 2008 Author Report Share Posted October 19, 2008 Yeah, i've been reading this forum for the past several days solid. Lots of good information. Going to ask on the nissan forums also about the dimmer cable. Also what benefit does the speed wire offer? I want to keep this installation as simple as possible, adding this wire makes it a pain.

Flipper Posted October 20, 2008 Report Share Posted October 20, 2008 It has something to do with the Nav being able to give you a more accurate estimate of your current location when you can't get a signal (I think) Like when you go into a tunnel or whatever. Just get off your lazy butt and hook up the wire and stop looking for shortcuts hah. I thought it was a pain too. Quote Link to post Share on other sites
ebbro Posted October 21, 2008 Report Share Posted October 21, 2008 In the installation manual it says the speed signal input is unnecessary for the F700 and that the extension lead is not included with the unit. Does the F700 not make use of this feature? Quote Link to post Share on other sites
Ravage Posted October 21, 2008 Author Report Share Posted October 21, 2008 I say then it's used for the DVD player to make sure that you're not moving when there is no GPS signal. Quote Link to post Share on other sites
