Look for a software solution with a Car PC of some sort. GPS provides the altitude feed much more accurately than barometric pressure used in the SURF and the data is included in the NMEA sentence it sends to the PC.
For inclinometer, you need a 3 axis acellerometer.
You may need a Arduino or some sort of embedded controller to parse the data and send it to the PC.
FYI both of the required sensors are in the latest phones and there is software that does what you want for the Iphone.
So Car PC or Iphone and no hacking the dash!
