Radio Arial and head unit wiring. HELP PLEASE

[adamk]

Hi, Since I have had my FD the radio when switched on in any source brings the arial up??
 
It should only come up when selected to radio should it not?
 
Anyway its doing my nut so I have ripped out the unit in an attempt to sort it out!
 
The unit is a 1 year old Pioneer, the units wiring diagram shows that the auto relay arial supply is blue I follow this through the loom all ok! ( turns out is hads propper nice looms fitted no nasty chops!)
When the radio is turned on and arial is up (again any source) when this blue wire is disconnected the arial goes down? then back up when re-connected?
 
Its almost that the radio "arial" supply can also be used as a remote on/off for other equipment ie amp, this is also supported with the units "fitting a remote amp" section.
 
This has got me scratching my head!!! can anyone tell me what the standard wiring is and please point me in the right direction, also what colours go the the mast/arial?
 
There are no other spare cores that can be used from the unit, I can only guess the loom is incorect for the car regarding the mast/arial control.
 
Please help
 
Much thanks
Adam

ive had the same thing it\'s much easier to send a 12v+ or ground when the unit is on rather than when the tunner is, i think a lot of them are that way unless you want to open the thing up and get rather techie you have no choice

I think 99% of radio\'s now have the aerial up as long as it\'s on, mostly for Traffic Announcements and RDS updates and stuff, so if you\'re listening to a CD and then the Traffic will come on instead.

Easy way is to just wire in a 2 way switch (about 90p from Craplin), then you can choose when to have the aerial up or down. I\'ve done this and it\'s handy for when local aerial down, CD\'s / MP3\'s on, when on a longer journey still listen to CD\'s and stuff but have the T.A. on.

My kenwood is the same - arial comes up when the unit is in anything other than standby

Hum, ok thanks for your points.:wave
I have e-mailed pioneer tech support I cant believe an expensive unit like this does one not have this function output!:3Confused
 
If not then pioneer must be ****e!:Hammer
 
Ill let you know how I go on. I cant be doing with driving around with a huge whopping great CB Mast on the back of my motor with the Head unit on! it looks horrible!:2eek
 
Yes, It shall have to be a switch if not!, but its a sure bet some prat will rip if off if I park with it left up, unless I do some fancy relay type wiring to make it come down with 12v supply off even with swith on type of thing??? oh er!
 
For now I shall hang a huge pair of pants to hang from my huge mast!!! LoL:driving
 
Cheers

just find out if it positive or neg switch hook that up to a ignition on supply so if you do forget the switch it goes down when the ignition is off

Hi

My Sony head unit only sends the 12V signal out to raise the mast if the tuner is selected.  It does however put the ariel up all the time if Traffic Announcements is selected.

Sorry it\'s not very helpful to you, but it maybe worth trying to turn the TA setting off as a last chance.

i have fitted quite a few pioneer head units over the years (just put mine in the rex yesterday) and they all definatley make the aerial come up as soon as they are turned on no matter what source they are on. pretty much all makes do this.

pioneer dont have the option that sonys have if the radio or cd is on ie the unit then the out put for the antenna is on aerial up .
a decent way round this why any one listens to radio beyond me all the interference . buy a digital unit have the areial inside the car no cb masts and have crystal clear sounds

[batman]

failing that its a switch to kill the antenna s power

[batman]

hope that helps

my car had a sony mini disc player when i bought it and that didnt go up at all but the unit still turned on.
 
i now have fitted a new pioneer unit and will not turn on if its not plugged in and comes up like other have said when its on anyting but standby :confused:
