Hi there, I recently bought a 2008 UK Honda CR-V EX model which was fitted with the original Alpine BB717PO Sat Nav CD FM radio. I upgraded it to a new Android system but I'm having a nightmare getting the new unit to communicate with the steering wheel controls. The original system used a green coloured 22 pin connector known as connector B Pins 3, 12, 14, 16, 17 and 18 have no wires, the rest do. Pins 4 and 5 carry 5 volts. My multi-meter skills end there. Would any kind soul happen to possess a wiring diagram for connector B? If so, would they be willing to list a copy for sale on eBay? They'd be saving an old man a lot of heartache. Many thanks, Gordon. .
