well after 1000 miles of crappy radio, just enough volume with MP3 player, i decided to get the BRP connect app.. on my phone,, so i made a play list of some songs,, and connected my phone, via bluetooth and all i can say is WOW.. 1/2 volume is all i need, and it sounds great,, finnaly happy with the sound.. also the forward and backward play works on the tank controls,, i was smiling today on my spyder,, whoohoo..life is good
