My setup:

Ram mount:
RAM-HOL-AP9 RAM HOLDER FOR APPLE IPHONE 4
RAP-B-166U UNPD RAM MNT W/ SUCTION BASE DBL ARM DIA
Mounted to the left of rear view mirror. Added zip ties just for extra safety (you will figure out how. Never needed them so far)

Dual xgps 150 with 5hz firmware upgrade
Velcroed on the dash middle in front of the vents.

Harry's lap timer: this app is awesome!!!

Need to get obd soon again. I had the kiwi with my old 3G but it didn't work well with the lap timer. I want to try again with 4s.

Hope this helps.
