hello, i came here because i have a problem with my radio on my sentra 2015, just wanted to see if any 1 else is having his worse nightmare with his radio, they just replaced it and the new 1 is Worse lol. the sound is at 3 on 40 and its Very loud, and i hear a weird frequency noice when the sound is turned off, i showed it to the guy, and he dosent hear anything(the sound wasent there before they changed the radio), i guess my ears are too sensitive. after that he pluged in his computer to reset the radio to maybe fix the weird problem that the sound is very loud when its not supposed to be, now the bluetooth dosent work anymore Lol. Seriously WTF. 3.8k$ radio hun, last time i bought a 200$ radio at canadian tire it was working so well.
