I downloaded the iPhone app and tried the demo. And then when I went to register, it told me I already had an account.
Upon further investigation, it turns out this is the same company as CarLink - Audiovox. I had researched this when I had my F350 and created an account then. It was on my short list to buy but lost out to the Viper SmartStart. Same approach. They both put a GPS enabled cellular connected micro under the dash. I had my SmartStart for about 6 months before trading in the SuperDuty. It's really a novelty item as I can start my truck without it just using the key fob from most windows (home and office). It was really only useful when flying back into town during winter. I could start it while the airplane taxied to the gate.
One important note... It's NOT two way, so if your truck fails to start (like my heavily tuned 6 liter Deisel) then You will never know until you walk up to the cold dead hulk
