I have installed an aftermarket combination NAV/Radio unit and everything seems to function correctly except that when I turn on the Boxster's headlights, the radio's display goes blank.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hope I've posted this in the correct forum. Can someone tell me what color wire in the Boxster's radio harness allows the radio to determine if the cars headlights are on? I have installed an aftermarket combination NAV/Radio unit and everything seems to function correctly except that when I turn on the Boxster's headlights, the radio's display goes blank. Thanks, Ken 97 Boxster

POST 3 / ORIGINAL POSTEROriginal post

Thanks for the reply. Unfortunately the boxster's radio harness plug was previously removed so I cant match the wires I have with their old locations in the plug. I was hoping to find a wiring diagram that showed me the color code of the particular wires. I have obviously miss-wired something because when I turn on my headlights the head unit cycles erratically. I guess the most likely thing is the connection to the illumination sensor, but I don't know which wire that is. I think I must have something tied to it that should be ground and then when I turn on the headlights it goes high. I sure wish the boxster's radio harness plug wasn't removed on the last radio install.

POST 4Original post

Grey and blue. That's for mine (2001). For 1998 (possibly yours), there's also a grey/blue that goes to terminal of the same name. So I'd look for grey/blue if I was you.

POST 5 / ORIGINAL POSTEROriginal post

With the info you gave me I was able to resolve the problem - Thanks Norm

POST 8Original post

Apologies for resurecting an old thread here...I'm having the exact same problem after installing a double din head unit and wondering if anyone knows how to fix it? The OP mentions they fixed it but didn't really say how...

This is a source reference. Confirm exact model applicability in the original material.
