On my Aspen I replaced the OEM nav system with a Pioneer. I lost the function of the auto headlights, I think they use the same sensor as the GPS, it had 4 wires on the plug, which was right in the middle of the dash, any suggestions would be appreciated, or something I could try, thanks

 

the auto part is a mux return to the cluster. Has nothing to do with the radio. U should take it to the dealer to see if u by chnage shorted out the front controler when u were messing with the new radio.

 

Have you checked any of the fuses?

 

Check fuses all ok, hooked up old radio everything works fine again, so it has to be something else, where does the auto H/L sensor at?

 

You may want to try checking out this link. It may be of some help to you, not sure? Worth a look anyway: http://www.lxforums.com/board/showthread.php?t=16999 If it does not help you. I would do what the Tech suggested. Good luck!

 

Thanks, but I already have the auto H/L, but my wife's Magnum doesn't so I will try that with hers.

 

This link may help a little. Worth looking at anyway. Good luck!

I'm sure why, but after I disconnected, and reconnected my battery the auto H/L's work just fine now, thanks for everyone's help
