This was an upgrade in my Volkswagen GLI sedan to replace the stock stereo and CD player. I really like this new stereo unit because it is in color, has touchscreen capability and the AUX inputs for USB, SD Card and iPod were what I wanted. The installer did have to use a special bracket to get it to fit in my car, but they said it wasn’t a big deal…most cars need them for after-market stereos. The sound and power seem good throgh my car speakers. It seems to have a little more volume/power than my stock stereo did. I also like the Bluetooth with my phone and Pandora radio, that works and sounds great. Overall, I’m very happy with this upgrade.
