Hey Dave,
haha, def will be happy to help stuff sorry set it up.
It actually works pretty good. It all works of GPS signals, so as long as you set your start/finish point its good to go. You also only have to do this once. eg I set Oran Park on it, used it on the GP circuit, went back 4 months later to do a south circuit day and it remembered the point and simply started timing laps once i turned it on.
Given the the iphone's GPS is not the best you do get some odd laps, but in general its good to see how you go across the day.
For $5 (what i paid when it was first released) its pretty decent.
Unfortunately it doesn't seem that Wakie is on his list of pre-programmed tracks. Will shoot him a mail about how to get it added, so far he's been very good with set up help.
