New VDO HU with Steering Remote ?

[hjmonaro]

I have been looking to buy this new VDO DAYTON CD2737 as it has everything you could want usb bluetooth etc and programmable steering wheel controls do you think it will work on the VS SII Calais system as I not up with their terminology CAN-bus or RC3. There on sale at Repco.
This is from the user manual,
Wires of Steering Wheel Remote Control (SWRC)
Some main functions of this headunit can be
operated from your existing in-vehicle SWRC, if
available and suitable for usage. If your vehicle’s
SWRC is based on 2-wire RC-3 compatible
configuration, it can be directly connected to the
headunit’s pair of SWRC wires.
Please program the headunit to recognise
your vehicle's SWRC commands first before using.
You may need to turn on the SWRC inside
the Software Access Menu (SAM) after programming.
Please check the SAM.
In case you are not sure of the steps, please
contact your dealer for assistance.

Steering Wheel Remote Control (SWRC)
This headunit is specially designed with a programmable
Steering Wheel Remote Control
(SWRC) to suit your car built-in SWRC as much
as possible.
Important note: This function supports SWRCs
that are based on analogue RC3-standard
only. Other SWRCs, especially those based on
CAN-bus, are not supported. For these SWRCs,
please consult your dealer for a suitable converter,
if available.
