Flat battery problem after installing 9000-1 - any suggestions ?

[clip]

plug and play all the way for me. Only thing is (as I mentioned before) if you don't tell your dealer about the error code coming up (system can't find radio), then they will disable it so it doesn't keep throwing up the error code. But then you lose steering controls and the unit won't switch off/on when you turn the ignition key on/off. My dealer just did it again so have to take it back into them

other than the flat battery issue are you happy with the AVC?
has it met your expectations

kind regards

Hi - generally happy - stanav screen directions work fine, bluetooth works fine, changing radio stations on a long drive where the stations change not very intuitive/easy to use whilst driving but that may change - have not yet used audio on the nav or tried the bluetooth steering wheel controls - car has now spent more days at Bill Buckle service than I have driving it though so hard to comment..will let you know what they say tomorrow !

cheers

Clip - Hi - I will pm you - at this stage I would be happy to lose the steering wheels control if your dealer can tell Bill Buckle how to turn off the multiplexer thing which is draining the battery !!

cheers

Clip - Hi - the dealer says the audio unit is shutting down but the canbus multiplexer is not (I don't know if this makes sense)?

Any suggestions on how to to test ?

thanks

Sounds as if you need an installer who knows his business !!

Have you spoken to Marty at FHRX ? He quite resourceful you know.

I don't have the AVC9000-1, but I'm sure the connection is the same. You would have got an external adapter that plugs into the back of the unit which then plugs into the VW plug.

Now if you're steering buttons are working, then all is good. The dealer hasn't disabled it. Therefore the unit should be turning on and off with the ignition switch etc as well - so not a problem with the car.

As for the can bus multi-plexer thingy, I think what he's saying is that power is still available, as it should be, even when the unit is off. For example, with the unit off, when you engage reverse the unit senses a video feed and switches on and displays the video screen for the rear camera (it then switches off when you take it out of gear). BUT, this should not work unless the ignition is on. Is yours working with the key out of the ignition? If it does, then it means it is still getting power (and hence your flat battery).

But forgetting all that, I reckon that the most likely cause is a bent pin or bad connection at the adapter point. Either that, or the unit itself does have a fault. It's a 10min job to pull it out, so might be worth having a look yourself.

The problem is nothing to do with the car but the head unit itself hasn't been installed correctly or it's faulty. The VW headunits have constant power to them but enter a sleep mode when directed to by the car.

Mate, this car never ceases to amaze me!

Maverick,

You've insinuated numerous times within this thread (five by my reckoning) that the installation itself is the cause of the fault and that the car should be taken back to the place where the aftermarket unit was installed. As stated in the initial post of this thread; we are the people who installed it, the car is presently here and you can rest assured it has been checked and re-checked and there is nothing untoward regarding the install.

On another note; you'll appreciate from the images below that there are only two loom plugs that interface with the car itself - the main loom plug and the aerial plug. Both of these plugs possess specific shapes and lock clamps making installation of them upside down or backwards impossible. In other words; it's going to somewhat difficult for any installer to get this wiring wrong - period. You'll also notice all the pins are straight and are not bent in any way shape or form.

So I'll thank you in advance for not insinuating that our workmanship is the cause of the issues at hand here. To everybody else; we have another deck here now which we are going to try. Either Vincent or I will keep you informed of our findings.
