A:AnswerThis is probably just because you're on speakerphone in your car - the phone probably auto sets itself to speaker if calls are being played through bluetooth. That will pretty much always sound like a wind tunnel without proper noise-canceling.
A:AnswerNot at all and the sound quality is far better than others I have used. I travel allot and have had issues with other transmitters picking up stations or disconnecting around semi trucks or ambulances. I’ve never had those issues with this model. Definitely worth the slightly higher ticket price.
A:AnswerYes it is, you just match the FM station on your car radio with the one from your Anker ROAV - SmartCharge F2 FM Transmitter.
then you send music via Bluetooth from your phone or any other device.
A:AnswerVolume wise I’d say it’s pretty good from my end. The stereo you have and the phone you have definitely plays a role in the sound output. Usually, if you don’t put your phone volume all the way up, you can hear static in the background. Putting your phone volume all the way to the max solves this issue and from then on it gets its volume from your actual speaker system.
