A few comments so far.
I think it will fit. I've identified all the wires and i think I know where they go.

I plan on using the pre-outs which are 2v standard as is the Saab/HK amp.
I have the iPod/iPhone link on order. I don't yet know whether to route it to the glovebox or the centre cubby.
I've decided not to fit a link to the steering wheel controls. It's expensive and it still needs soldering/crimping and in the end it will only do the volume really. Maybe one day I will.
But the Recommended price of the head unit seems to be around £800 in the UK. I got it from a car place in Hayes, Middx for under £650 and picked it up there this afternoon as my wife had to go down that way anyway.
What I find puzzling is that Halfords are offering this unit for around £1100!! So is Argos!!
But all that pales into insignificance when you realise that a replacement Saab Denso OE unit can be had for a bit over £2300 - daylight robbery! And it's very out of date, and can't be customised. Mine is broken and a new DVD drive can be sourced for around £300 from Germany. The ribbons are bonded so fitting a new drive would not be DIY. So I was estimating £400 to repair and end up with something from the 90's.
ApArt from all the extra features, I will be able to remove my Parrot bits and the DAB add-on that sits by the passenger's knee - she complains!! I will also be able to customise the Points of Interest, and SWMBO will be able to use it while the car is in motion to reroute around a traffic jam.
But that's all for the future. I have to learn to install it first!!
