On another note the various coding options from the cheat sheet work well. Couldn't find the weather band code though. Anyone else try this one?
That's the same cable I got from amazon for $8.95 plus shipping. I also spliced 1/2 of a ground-shielded cat5 patch cable to it with a 510 ohm resistor and the appropriate ground connections; works great.

The ground-shied is a good idea as the laptop is not otherwise grounded to the car when you are connected to it. It's not absolutely necessary, but it is good idea.
