I'm using this. Turns on when I start the car and auto connect to the head unit via WiFi. Works a treat, hoping it will be able to run a Kogan SIM card

Yeah, tot of using 3G auto connection too... wifi is superb but 2 clicks everytime is just too labour intensive! =)
Anyway, 3G rates in Oz is a rip off... so im stuck with wifi through phone hotspot... for those in Oz using 3G.. any good deals?
