I don't have a radio in the Supersports and have been using a rechargeable dab radio with 3.5mm aux in for those tedious motorway journeys
I can use my mp3 through this set up.
However unit not loud enough above 60.
I wont use headphones in the car and have been looking at JBL Charge 3 portable rechargeable speaker and the Bose soundlink mini
Any comments/options/suggestions please other than keep speed below 60 !!!
