Great sound upgrade
This is a great sound upgrade, would def it give it 5 stars but it really needs a few things fixed to make it actually safe to use - as it is an app for a vehicle system.. It does not work with Apple Music - which means I have to switch apps all the time.. once setup, this app is the only control for the volume, then I have to switch apps to select track or change song.. then back to adjust volume.. which brings us to the volume control .. needs a big improvement. - it is very very slow, so many taps to go up or down, no slider. And the remote is even slower. If the volume could be picked up off the phone buttons or within the Apple Music app slider it would make it much better. These problems make the app extremely unsafe to use while driving, even with the phone in a cradle, there is just way too much fiddling required for its most basic operation.
