Hi I'm new so apologies if this is in the wrong section. I've been getting what sounds like mobile phone interference noise in my car, the bzz bzz bzzzzzz noise. I have an alpine cde w235 bt head unit and an 8" alpine subwoofer. The interference isn't always there but is there more often than not. I have also noticed that it can happen when my mobile is in flight mode. My phone is an iPhone 7 if that makes any difference and is always connected via bluetooth. Any ways to stop this noise happening as it's really annoying
Thanks
Thanks
