Cool - spent another half hour last night soldering the connectors onto the numerous leads that protrude from my new tuner and tested it in the car. It worked first time - Hurrah!

Another tip for you kit builders out there - don't get too much solder on the pins for the tuner connector as that makes it very difficult to push them into the housing. Also you'll end up with two blue wires - only one of which is shown on the wiring diagram. It's not made clear which one should go in the connector - it's the 12v wire (NOT the power antenna wire) which connects to the bottom hole on the PCB.

Quite impressed with the tuner facility - the scrolling RDS info showing details for the current radio programme is pretty cool.

Top stuff.
