I have received 3 different Via 1505 and NONE of them are recognized by my PC, nor can they be charged by a USB ( tried different chords), or by my car . I paid for a new one, but believe they are sending me a refub one each time. Not sure at this point if a new one will work any better. Hard to believe I got 3 bad ones, not sure what to do now besides ask for a refund...
