oh i didnt read into it that much. Are you sure? I thought it picked up a GPS signal anywhere, but the 150 ft thing was just to get it to beep or something.. idk... guess i didnt read through it enough.
I'm pretty sure my bike was 150 feet away from my house in the garage across the street. Would of helped me. Having the find my iphone app updated would of helped me to. Just charge an ipod and keep it in the bike, it'll get you close enough. ha.
