Tahde Posted September 24, 2006 Report Share Posted September 24, 2006 I just got another Z1 installed in my 06 Trailblazer SS and when I turn on my headlights the nav wont dim. Could this be becuz I have daytime running lamps? I also dont have any chime. Could anyone help me with this? Quote Link to post Share on other sites
ducatiboy Posted September 24, 2006 Report Share Posted September 24, 2006 For it to dim, you need to find your car's ILL wire. Or at the very least, find a wire which goed to 12v when you turn on the headlights... I suppose if worse comes to worse, you can tap off the positive lead to the tail lights. As for the chime, I have heard vehicles like yours need some adapter for the chime: [url=http://www.crutchfield.com/S-h8lPzMQ9QqJ/cgi-bin/prodview.asp?i=120GMOS04]http://www.crutchfield.com/S-h8lPzMQ9Qq ... =120GMOS04[/url] Quote Link to post Share on other sites
PaisanNYC Posted September 24, 2006 Report Share Posted September 24, 2006 sorry to hijack a thread, but a stupid question. I definitely do not have the ILL wire hooked up on my N3, but if i go under an underpass or through a tunnel, the lcd does dim and gets brighter as I reemerge from the momentary darkness (without my headlights going on). Does the N3 have some sort of sensor for this as well? It's very strange but cool for when I drive through the tunnels into/out of Manattan :) Quote Link to post Share on other sites
ducatiboy Posted September 24, 2006 Report Share Posted September 24, 2006 The N3 has that feature and the Z1 does not. The only way the Z1 will dim is for the ILL wire to be connected and to turn on the headlights. Quote Link to post Share on other sites

A1cntrler Posted September 24, 2006 Report Share Posted September 24, 2006 A friend of mine has a Silverado with the Z1, and his installer told him that the ILL wire cannot be hooked up, as the dimmer for the factory headunit ran off of a CAN Bus system, meaning that it is computer controlled. The AVIC I put in my '07 Sport Trac ILL wire did not work either. I overcame it by tapping into the light under the center console where the shifter is at. I tapped into the light that illuminates the PRND12 on the shifter. Comes on when the auto headlamps come on and off when they go off. Works good. Quote Link to post Share on other sites
attilas Posted September 24, 2006 Report Share Posted September 24, 2006 My installer set it up so that I can dim the screen using the dimmer switch for the inside lights of my TBSS. It works kind of. I seems to dm a bit as i turn the knob. However, the thing that is neat is that the screen reverses colors when I dim it all the way down. ie white goes black. So then the screen is mostly black, with the roads being colored lines etc. Kind of looks like a negative image. Anyone else done this? Quote Link to post Share on other sites
cntrylvr79 Posted September 25, 2006 Report Share Posted September 25, 2006 The negative image you're talking about is what the avics do normally when the ill wire is hooked up. Quote Link to post Share on other sites
Tahde Posted September 25, 2006 Author Report Share Posted September 25, 2006 Cool! Thanks alot guys. I'll make sure I'll relay this to my installer. I would LOVE to do this myself. But I just have this luck I'll screw it up. And with me just getting the truck (wednesday), I dont wanna mess with those wires. But basically the best way is to hook it up on the taillights?

You want 12V when the lights are on and 0v when they are off. I figured that worse comes to worse, you can tap off the tail light bulbs. Most poeple know where they are :) But there is a wire in your car behind the dash somewhere which would work, but I don't know where it is. A good installer will either know or know how to find it.

Do you have one for this problem that I have? Quote Link to post Share on other sites

I can admit I've done that in the past when I've been pressed for time. Quote Link to post Share on other sites

I want to go outside right now and fix this. But I just dont have the courage. lol. I"m going to have my installer tap into that reverse wire as well. Its kinda funny, but my camera comes on when its in drive. Doesnt come on at all when its in reverse unless I manually do it. So when I talk to him tmw, I can tell him exactly what to do now.
