It tries to work I travel to Sunnyvale  CA for my work so there is plenty of stop and go traffic along the way where a song doesn't need to be as loud as it was at 70mph. The problem is that this app doesn't seem to work well when it's not running in the foreground. Often I found that while it's resting on the dashboard mount that's out in the open for all satellites to reach it  I'd go to the app and see it's waiting for gps signal... and waiting.. and waiting.. Ended up uninstalling until it. I'll try again if I seen it gets updated. T-mobile HTC One  4.3
