New Head Unit

[benno9911]

i bought a new head unit and now my aerial up and down buttons are not working its all wired up right is there anything i can do to by pass the head unit

[nugatory]

There is a wire that sends the signal to the aerial. On your new head unit you might've had a wire called "Power Antennae" and on Kenwood stereos this is a blue wire. It sends a signal to the BCM and then the BCM controls the Power Antennae.

When it doesn't receive a signal, it's always in the "down" position meaning it'll always return back to down if you press the up button.

You didn't mention it, but I'm assuming your car is a high end bcm meaning it's a Berlina, Calais or Statesman.

I've only got an executive with a low end bcm but I upgraded the power antennae on my car to an electric one using the power antennae and power antennae module from a VP Calais to bypass changing the bcm.

To bypass your head unit (if it's missing a power antennae wire) you hook the wire used to signal an amplifer instead. This is an external 12V+ wire.

Looking at my wiring diagram, there should be a yellow wire (with red trace) that goes to the bcm, i believe this needs to connect to the blue wire on the new headunit. Let me know how it goes i'm trying to suss it out now before i install mine.

Cheers!

Why worry about the antenna and stereo if ur motors stuffed?

Well there's your problem, lol

I think he means the aerial motor.

I think he means the aerial motor.

Would think so lol

Would think so lol

Sorry, I thought you thought he meant the car motor and why was he worrying about the stereo when the engine is stuffed.
