Bandit, I'd go with the CP9110. Unless there IS a way to make the Aeroforce work....highly unlikely, but I think it was talked about briefly as a possibility once (you were going to be the guinea pig for that at INTENSE).
The CP9110 is bulky and it is not easy holding it while driving (I've driven one-handed several times with it testing for KR and it wasn't fun at 80+mph). But it shows everything you need. Finding one can be an issue though. Cables can be bought cheap from Slug.
I thought of trying to mount the CP9110 in my car, but any way I could have done it wouldn't have been discreet.
I believe Slug was trying to get something to work with laptops as well. I'd shoot him a PM either way.
