I uninstalled this after just a month. HD radio tuners replace the tuner built-in to your stock radio is my first complaint. especially because the sensitivity of the HD300 is higher than my head unit. Second and most important is the switching. It's SOOOOOO ANNOYING!! If an HD station was available it plays it and it sound great but then you drive out of range and it automatically switches back to analog which sounds ok, not bad but the transition is really a deal breaker. And yes, within your radio you can disable auto switching but I found with my head unit (JVC KW-XR810) it goes back to automatic on it's own.
