Well, i got another bread board cleared now so was thinking about wiring up a simple CAT for the VT - VZ's so the steering wheel controls can be used with new head units without having to pay $150-200.
I've got the circuit designed in my head atm, however i need to know what voltages or even better if you know the restiances that are outputted from the Steering Wheel controls.
I have this data from Holden for the VT - VX's:
Resitance for functions:
Volume Down - 0 Ohms (Or negligable)
Volume Up - 1k5 Ohms
Mute - 3k7 Ohms
Preset Next Down - 5k Ohms
Preset Next Up - 9k7 Ohms
Mode - 19k7 Ohms
Could someone with a VY or VZ check to see that that's what they return for our switches too? I dont have time to check at the moment.
Voltages probably make my life easier actually, or if you can tell me how much current goes through the controls to the head unit.
Once finished they shouldn't be more than $50 including postage, and will be all programmed for each head unit brand. Re-programming will be available for cost of postage too. :yeah:
