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

[ploz58]

thanks folks for the "balanced" discussion,
i had just ordered an AVC through rob apparently a new shipment arrives tuesday which has the usb port on the front.
Rob was very honest had mentioned that some people have had trouble but a new head unit had been sent up to help investigate the battery drain.
so no blab blab blab sales talk he appeared to be right behind his product

after reading the current thread and going to all the other sites, i thought id done the wrong thing, but getting a balanced view restored my faith.
Im fully aware of you get what you pay for.

Thanks again, and keep up the good work and i appreciate the experience out there
regards
Phil.

Back on topic, what was the problem vincent?

From the post I saw on golfmkv he had returned the car to stock and returned the AVC9000. I assume the replacement had the same problem???

We will never know except that the stock head units don't have a problem

I contacted Vincent on Friday (21 Aug) about it and he's waiting for Rob to send a replacement unit to be installed. FHRX pretty much isolated that it was caused by the headunit, even though it was actually the CANBUS multiplexer that wasn't turning off and was drawing about 0.2A per 12 hours. Once they have the replacement they'll be able to tell if it was just that particular headunit which was the problem, or if it's a fundamental problem with the design of the headunit (therefore all AVC9000-1/WD6050 headunits will cause the same multiplexer problem).

So in summary, it's still a "watch this space" case here...

ive just purchased one of these units from rob,
but as yet had not had it installed,

Im hoping this is an isolated issue,

Any suggestions on how/where to locate the GPS antenna,

kind regards
Phil.

Do some search in Golf5 and Audio section there is a lot of info there about the unit and from my reading it is not all the gloom and doom only. Some owners are quite happy with it.

Hi one and all

Ive been following this post and a few other, re the AVC9000-1/WD6050. There are about 188 and counting pages of info on the golf markv forum. My take on the power drain issue is it is a CANBUS issue with certain model VW's.

It's actually an issue with the aftermarket headunit not the car.

VW send signals via the CAN bus to switch devices like the headunit on and off, if the receiving device does not power off that is the fault of the headunit or the installation of it.

Poor reverse engineering of the CAN bus signal is the reason for many of these problems. Other problems can come about during installation with poor connections to the CAN bus network. There's information here on repairing the CAN bus network which gives an idea as to how wiring and connections should be made.

The only problem with factory headunits is where an older model series PQ35/PQ46 (MY08 onwards is fine as are quite a few MY07) has a third generation headunit (RCD 210, RCD 310, RCD 510, RNS 310) installed (excluding the RNS 510) and this requires a CAN bus gateway upgrade which is a $300 project.

Remember that the third generation headunits didn't appear until the MY09/MY10 models so the ability to fit them to a MY06/Previous Series is something you generally wouldn't see from other vehicle manufacturers. But as I said don't confuse this problem with issues with aftermarket headunits.

Info on the problem is in more detail here.

Is there anything wrong with the vehicle prior to installation of the aftermarket head-unit ?? Answer NO

Therefore there is NOTHING wrong with the CANBUS, there IS something wrong with the aftermarket head-unit in that it's installation does not work correctly with the manufacturer's (in this case VWs) system.

You can't expect the manufacturer of the vehicle to set it up specifically for some aftermarket unit, you CAN expect the aftermarket unit to be engineered to work within the system provided.
