Antenna dramas after replacement of stereo

[bcw61]

Hi.

I have read a similar problem in the VY forum, but thought I would ask here directly, as there may be some differences between the VY & VZ. I have just replaced my Blaupunkt single stacker cd player with a Blaupunkt six stacker cd player on my VZ executive wagon, but the antenna will not extend when the stereo is turned on. Operating the antenna extend/retract buttons on the new six stacker does nothing. I put my old single stacker back in & the antenna works fine. Unfortunately, I don't have an operators manual for the new six stacker, so I'm unsure if there are some settings that I need to change on the new stereo. Has anyone got a possible solution to this problem?

Cheers

PS. Would it be possible for someone to send me a copy of the Blaupunkt six stacker cd player operators manual please?

Oh no, I think i might have the same problem, I've just replaced my single to 6 stacker on the Vz and i get no sound / movement with the areal.
Then again my areal was faulty with the single stacker and i'm not sure until i change it back if that was the issue.

did the six stacker come out of a monaro with the diversity antenna?

[bcw61]

No. I got the new six stacker off fleabay. Checked out the connections on the label on both single & six stackers, and they are identical - including the 'ANT TRIG' connection. The new six stacker states 'Type: SYS 4', whereas I'm fairly sure the single stacker states 'Type: SYS 1'. Are there any differences in the antenna connections?

[Phyco]

I think if I remember correctly, the antenna itself is actually the difference on models with the Single Disc Unit and Models with the Six Disc Stacker. One of them remembers the position it was in last time and stays there. Don't take this as solid advice but if you reconnect your Single Disc Unit, wait for the antenna to raise completely and then disconnect it, you may have fixed your issue.

[bcw61]

Thanks Phyco. Now just have to try to get access to the antenna power leads, so I can disconnect them. I've traced them into the lefthand footwell & they disappear behind a silver module. Haven't tried accessing further, as I'm unsure what this module is & I don't want to muck around with it until I know what it's for.

[bcw61]

BTW, if anyone has a copy of the Blaupunkt six stacker cd player operators manual, I'd really appreciate if you could send me an electronic copy. My email addy is: bcwik@internode.on.net.

Cant see that idea working, the antenna has constant power and only extends when the radio 'trigger' wire is active otherwise it will retract. good thinking though! i think your right about different antenna's between models..

Thats the PCM (powertrain control module) runs the motor and controls the gearbox

what you could try doing is hooking up a switch connected to an accessories power source to the 'ANT TRIG' wire..

[bcw61]

OK thanks for the replies. I've managed to track down a factory circuit diagram for the VX audio system. Looking at that, for a standard Executive type audio installation, there appears to be a couple of wires directly from the headunit to the antenna that bypass the BCM. If the VZ has the same setup, I'm hoping that if I manage to disconnect these wires, then the new 6 stacker will then be able to control the antenna via the BCM instead.

BTW. Can anyone provide the audio system circuit diagram and associated connector layout for a VZ?

[andyman]

i think you will find the antenna is operaterated solely by the head unit,

i think you might be right by earlier with the different anntenna setup + youll have to run a seperate wire from the headunit to the anntenna

[bcw61]

I also assumed that the antenna is controlled solely by the head unit, but I compared the single cd & six stacker head units side by side & they have identical pin-outs. I still think the clue may lie in the type of antenna control signal that each type of head unit puts out - this seems to be indicated by the slightly different antenna to head unit wiring between the Executive & Berlina/Calais models for the VX & VY. The Berlina/Calais models for the VX & VY appear to have the antenna signal from the head unit go to the BCM (using the BCM to then control the antenna), whereas the Executive VX & VY models have an additional bypass to allow the output from the head unit go directly to the antenna.

If only I could get the VZ audio system wiring diagrams to confirm my theory. LOL

[Pete_perth]

Looks like we have a few people working on this antenna problem. I have been trying to solve it for a while. My theory is that the single antenna wire coming out of the head unit sends a signal (either voltage or frequency) or an actual data packet that commands the BCM to control the antenna. However, I have tried a number of voltages and none of these seem to make a difference. Will share anything I learn in the hopes of finding a way to replicate the instructions from the head unit to the BCM so any aftermarket system can be made to operate the head unit with height control etc.

[bcw61]

OK. I will be looking at this over the weekend, to see if I can find a solution. Hopefully it will be as simple as finding the couple of wires that go direct from the head unit to the antenna, and disconnecting them. This should allow the new six stacker to operate the antenna through the BCM.

But somehow, I have a sneaking suspicion that seems far too easy. LOL

[bcw61]

Hmmmm. Turned up nought so far. Hopefully will have something by tomorrow night. Would seem to appear that the the 'ANT TRIG' has got SFA with the antenna unless wired up in the Executive 'fully up/down' mode.

[bcw61]

OK. Decided to have a more in-depth look at this. According to a VY circuit diagram I have, I seem to have all the wiring to the BCM setup for a 'high series model', as I have a green wire (I assume it to be to the antenna) at terminal D23 on the BCM, the grey wire on terminal D7 on the BCM & the yellow/red wire on terminal C10 on the BCM. I think this leaves me with two possibilities - the antenna is the wrong one for the six stacker (although everyone I've asked states that there is only one type of antenna fitted) or my BCM doesn't support the antenna variable height adjustment.

My BCM is coded '588 MID', so if anyone can confirm if this BCM will support the antenna variable height adjustment function through the six stacker antenna height adjustment switch, that would be great.

TIA

have you ever thought about ringing holdens to get a definant answer?
i know you could option an sv6 and possibly the exec with a 6 stacker from factory so i may just be a tweak with the tech 2 for that particular option

[bcw61]

Have rung a Holden dealer. Couldn't give me any sort of definitive answer. Might have to try the Holden National Care Centre (or whatever it's called), to see if they can give me an answer.

Well, have just had my VZ re-programmed with a Tech2 & the antenna is working OK now. The variable height adjustment doesn't work via the headunit, but at least the antenna now raises & lowers as per the single stacker I had.

Cost $55 for Holdens to do the Tech2 update.

Happy now. Thanks for the help guys
