Hi

My previous Alpine headunit would retract the electric aerial when you changed the source on the headunit to either CD or Minidisc. If you then changed it to to tuner, the aerial came up again.

 

I have had a new Alpine headunit fitted and this functionality now does not happen. The aerial is always up when the headunit is on.

 

Is this the same for everybody? Would love to get it back how it was, as I very rarely have the radio on so would be great if the aerial was down when the CD's are on.

 

Thanks to anyone who can advise.

And I want the aerial to stay down, not go up when listening to CD. ;) Since I only listen to CD's in the car, what's the point in having the aerial go up and down everytime I have the headunit on.

 

Yeah thats what I meant, depends how you read my reply LOL

The antena 99% of the time has a blue antena feed comming from the head unit, most stereos will only feed this to the aerial when any of the radio functions are on. If not it should not send a signal and the aerial should retract.

 

Most people who wire in antenas havent got a ****ing clue and wire it to the switch to the igntion or something stupid like that.

 

I would suggest checking the antena is wired to the antena on your head unit, chances are someone has wired it to ignition or something similar.

Aaah right it might be a bit more fiddly with that type of switch as it needs power for the light on it.

I would think if you cut into the head unit antenna wire and connect the head unit side to the switch positive and the other side to accessory, then earth to earth, it should work.

You shouldn't need a power feed as such.

 

When the switch is ON your head unit will control the aerial as it does now and the switch light will be on.

Switch OFF and the switch light goes off, the aerial goes down and stays down in CD or radio mode.

 

Thanks Chris.

You pretty much got it spot on, except I didn't need to actually cut the aerial cable. I just disconnected the positve red wire from the switch and all works ok. Earth to earth, and power aerial cable to accessory. Nothing connected on the positive connector. Works exactly as you described.

Cheers. :cool:
