As far as display goes, I have a head unit in my car that mirrors my phone. Essentially I am trying to get the data acquisition with a clean integration into the car. So far it is a work in progress though I am getting better with each event.
The problem with the data I had from my spin was that the accelerometer data was bad from the mount having too much play and the GPS was nearly useless except for general lap times (no decent correlation with exact on track position).

Save yourself the headache and just get dedicated unit. While the phone apps will give you accurate lap times, data acquisition is unreliable. The root of the issue is that the external gps and obd2 units are WIRELESS. You will constantly get dropouts and disconnects. Been there, done that...
