Are you using the ignition feed at the head unit?

Nope , into the fuse box onto a couple of spare terminals

With it being CAN Bus, the fuse box most likely isn't just a fuse box. It'll
have a CAN controller built in, and chances are you've probably picked up
two fuses that are controlled by the CAN controller for optional extras.
Hence the strange goings on with voltages.

Professional installers will always take a feed direct from the battery, and
unless they can find a suitable ignition controlled wire, they'll wire the
kit up so it's permanently on. It just means you don't get the option of the
phone turning off with the ignition (most handsfree kits will work with the
igntion off anyway).

The fuse that I've used for the switched live is labelled with a phone
symbol , suggesting it's designed for a car kit.
The other one I can't remember off the top of my head.

Indeed.

I'd rather not have the continual drain , even if it is low.
Looks like I'll have to try and find a route through from the engine bay for
a permanent 12v though

I would personally take the feeds from the back of the barrel. Good
luck with it whichever route you go.

Now this is a total mystery to me. It seems to vary from week to week the
situations in which it will and won't power up and I'm checking all the
connections with a multimeter and it *is* getting power. Why should it be
happy with 12v in one place and not in another?

It's that dodgy Czech build quality.

Should have bought a proper VW rather than a cheap Commie copy ;-)
Trying to wind us up again Steve ;-)

I need new bait, Zoidberg appears to be immune to the stuff I'm using

I didn't bother with the 12v switched when I last fitted a car kit- just
pggybacked it all off the fag lighter- and never had any problems.

Be careful - I had to call out the AA a couple of weeks ago - I have a
4-way adaptor in the centre cubby with sat-nav, phone and PDA chargers
plugged into it.

I parked the car up for 5 days or so, left everything plugged in, and
came back to a battery so flat, I couldn't start the car.

It's fairly old and stinky , and normally Zoidy will eat anything!

The carkit will power itself down if there's no phone connected, so I
wouldn't worry about it.

Chargers that plug into a accessory socket generally remain active all the
time (ie. LEDs usually stay on) when plugged in, whereas proper phone kits
are designed to power down to minimum power if not being used.
