Is it worth starting a new thread?
It might be best to start a new thread Mate, seems this one has died a death...
It's really not that hard a job to fit the screen and I'd have no worries about doing it to a car that I owned, it's just that with your car if anything were to happen then you'd be stranded a long way from home!
Plus the Chap with the TechII thingie whom I was hoping may be able to lend a hand has no experience with the Bose set-up 

Also, without seeing it, I'm unsure of the exact wiring fitted to your car.
I'm guessing you have just one wiring connector on the back of your screen?
It may be grey in colour with around 30 odd wires attached? From what I can work out I'd HAVE to splice into this loom on your car.
The colour screen in my car has two connectors going to it a large 32 pin grey one and a smaller black one, the black one is mainly fed from the stereo but three wires are spliced into the grey connector, also this grey connector has had a few of the wires snipped and left disconected...
As said by 'The Boy' it would be easy to modify a TM loom to supply the black connector,
I do have a spare traffic master loom knocking around, the diagram below may help to illustrate...

...it shows the three block connector fitted to the rear of your stereo, I think you said you have a
CCR2006 headunit fitted in your Mv6, these have double the amount of pins in the third connector so are
labelled from 17 to 36. First connector (block 1-8) deals with power to the stereo, second connector (9-16)
is for sound output, only the third connector (block 17-36) needs major changes...
This is how the pins are wired in my car...
Pin No.   Wirecolour/tracercolour   location
17                brown/green             black plug
18                brown/white              black plug
19                 black                       black plug
20                not used                    ---------
21                not used                    ---------
22                not used                    ---------
23                not used                    ---------
24              Green                        black plug
25              white                         grey plug
26              brown                spliced to main h/u earth (pin 4)
27           brown/white          spliced to stereo feed loom
28               not used                    ---------
29           broken wire                   ---------
30             white                          black plug
31             blue                            black plug
32            green                           grey plug
33            white                           grey plug
34            black                    spliced to stereo feed loom
35            blue                     spliced to stereo feed loom
36           brown                   spliced to stereo feed loom
The only issues I have are pins 25, 32 & 33. Oh and possibly 29 but I guess it's just not used, like the other unpopulated ones...
25 and 33 are joined together then go into the screens grey plug via a white wire.
32 is green and again goes to the screens grey plug.
These white and green wires may not be standard but they do go neatly into the grey connector.
