Considered the app but I use streaming bluetooth for music. Wonder if the Iphone 4s will run the music on bluetooth and the guages app on the wireless, at the same time. I don't think so.

 

I have strict instructions from the GF,not to get silly, when she's in the car. Awhile back, during a weak moment[with GF and her sister in the car],I was zingging corners, on one of my fav. Nor-cal twisty roads, and had to stop to let her sister out to puke. Now, under strict orders, to only get silly, when they are not in the car. True story. "Moon"

 

silly Moon kix aren't for girls, at least she let you know to stop before she yakked over your shoulder

 

I make my family sick when I drive the backroads in Lancaster County, PA. Those roads are full of sharp twists and turns as well as vertical undulation that make a rollercoaster seem tame. I always love me some negative G's!
