I think you'll need the gadget.... As the RCD300 radio on the Golf V appears to be completely controlled by the CAN bus.
The only connectors are speakers, power and ground, plus an alarm lead, plus the CANbus twisted pair wiring. The CANbus is used for "lights on", "radio on" and GALA - there is no switched ignition wire, nor is there a lights on cable.
The connectors on the back appear similar to the VW Delta unit - not the Gamma.
Not sure if it is CANbus on the Mk5 or not but ?180 for a transducer is steep! We bought some for the SatNav's for work (Merc Sprinter Ambulances) and we only paid around ?80+VAT from www.huntertransducers.com They are not vehicle specific as CAN is a standard and it picks off the correct data from it and converts it to a pulse for the SatNav.
That's not the drawing of a Mk5 radio as it uses the new 'Quadlock' system. That's the 'Gamma' system in the Mk4's. I've had a look on the web for a pinout of the DELTA radio but can't find one! I do know there is a picture of it on the back of the radio though.
OK got can bus reader from orpington stereo ?121 ever body else wanted ?150/?200 looking at that nice drawing in German i take it the can bus high is pin 9 and low is pin 10 for the new mark 5 golf if it is the Steckerbelegung delta plug does anybody know if this is the correct plug ?
I have told the shop what its for a Mk 5 golf and it is so i can get the speed pulse for sat nav i also told them how i wanted to connect it up IE onto the radio plug so i will ask the question 2moro when i can ring them. They did offer me 1 that did everything dimmer and switched off when ignition was turned off but i have been using the radio for 2 months now no problem so went for the cheaper 1
I did read somewhere that if you take out the glovebox you can get to the CANbus wiring there also. Whatever you do though when you fit it, DO NOT cut the CANbus wiring and just pare back the insulation and solder it around.
The new VW Golf is CanBus the conection can be found behind the glove box top left, there are 2 wires twisted together, Colour Orange Brown (Can Low)/ Orange Black(Can High). Access is a bit tight but can be done.
