The Alpine INA-W910 is everything you could ever want and then some. This unit is awesome. If this doesnt do what you want or need it to do then what you want does not exist. Im thinking of buying another one just in case i buy another car that i can put it in. Its the easiest to use. Its the fastest to start up. its the quickest to connect. All that you need in one place. I highly recommend this unit.
