Does anyone else have a similar issue with their unit. Whilst connected to the unit via bluetooth and listening to my music through Spotify, the volume is considerably much lower than the radio. I have to turn it up every time, then turn it down before I disconnect the bluetooth otherwise I get the radio blasting in my ears when converted back, this is very annoying. Wondering if this is a common fault with this unit or if there is a quick fix or solution around it, any feedback would be appreciated, tia.

Sounds like settings in the back end .... either the audio or the phone, my bet is on the phone settings.

Can you try another phone to see if it happens on that also

Will try on another phone and see what its like.
