i have this also, got the unit from dx. using torque. very useful for long drive. Problem is BT version cant be used on ios, if not JB'd. very useful pang monitor, ng status ng engine, even yung FC, meron din. i'd say sulit ito, even bihira ko na sya magamit, dahil i've switch mobile phone to ios. nakikihiram na lang ang ng android sa wife pag need ko i plug itong scanner.
