I really wanted to like this. My old Camry still works great but has no Bluetooth. Alas, I was greatly disappointed. The audio level is extremely low. Even with my phone at max, I have to crank up my radio volume to 11 in order to be able to listen to the music. Then, when I switch back to the radio (XM) it’s extremely loud. If there the audio balance was at least close to the same it would be a great product. As it is though, it’s not worth the price.
I too wanted to really like this. But I also had problems with very very low volume from the FM signal to my vehicle receiver (about 8" away from the transmitter). What audio volume there was, also was of poor quality. I guess I have a charger only now as the transmitter is useless.
