Wanting to hardwirie the car kit so the hp1940 can have power without having to mess about with the cig lighter.

You can hard wire 12v straight into the jack on the left side of the cradle (dont forget to fuse it). The cradle then converts that down to 5v which comes out of the connector the your iPAQ sits on.

So it converts it down to 5v from 12v

Would it be better to hardwire it to 5v fuse then the pda only getting the recommand vots just incase the step down that build into the holder fails

No I wouldn't recommend that at all. Just put a 12v feed into the connector on the left hand side of the cradle as you have been with the cigarette lead.
