You will note that the connectors are totally different physically but the wiring is the same so all the wires are there.
Not quite!
As well as the wiring plugs being different, there are some other differences:
The wiring to the display (which has to be replaced, as ccrt700 has it has its own dedicated display) is different. There are only 2 wires, which are in place, but should really be shielded. I have tried it on the bench, and it seems to be OK on existing wires.
The wiring to the CD player (which has to be replaced, as the CCR600/CCR800 CDC2 changer is different to the identical looking ccrt700 CDC2 changer) is different. At least 2 wires are missing. I have further work to do in this area to find out what needs doing. Hopefully, if the Bose loom came from same donor as ccrt700, then the wiring should be in place from kick panel to cdc2.
The loom to the courtesy light (which has to be replaced with the ccrt700 specific one) is missing. Most of the right signals should be nearby, though the mic will need to be run.
Assuming your car is prewired for phone, the coax is missing from ccrt700 to kick panel is missing.
There does not appear to be an easy way to get a speed signal to the head unit.
Assuming you have fitting bose amp, speakers (all - the door ones are different to std), and loom, you may be better off fitting ccr800 which is plug and play to ccr600 once you've fitted bose loom.
