hyundai tucson audio streaming problem
 

hello eveyroneI own a tucson IX35 model 2015.
i have noticed when playing audio through bluetooth stream the sound is distorted but when making a regular call the quality is perfect.
i tried androind and IOS phones ,i tried to unapair and pair again but with no result.
many blogs speaks about this problem in hyundai headunits with no possible solution.
is there any way to fix this unpleasent problem ?
is there a way to replace the bluetooth in the main unit or even reduce the gain in order to have a proper signal flow ?
thank for any help
