I just purchased a 2010 low speed Mygig factory unit. The Fosgate speakers sound night and day vs the Chinese. The Chinese screen typing is more responsive than the mygig unit but that's about all the pro's it's going to get. The Chinese radio is not a bad unit, just not worth 600.00. Realistically it should be in the price range of 250.00 300.00 max. Too many glitches for the money and it should come with a manual, written in English, not broken English. And the tech support is worthless. You can pick up a Mygig unit for an additional 100 to 150 from oemautopartsco.com you'll be happy you did. The one I purchased was off E-bay, it has the U-connect (hands free talking) and is Sirius ready for 590.00.
