Car Bluetooth transmitter that goes below 88.1?
A few years back, I had a BT Transmitter could be set to 87.7. It was perfect because there were no radio channels on that frequency. Eventually it broke, but it was fairly inexpensive and lasted a few good years so I just repurchased the same one, only to find out it only went down to 88.1. It worked okay, except it was slightly fuzzier and sometimes other cars would interfere with it.
Now that one has also died, and I've been casually browsing for a new one. Most retailers don't have frequency ranges listed under their transmitters, and the ones that do, don't go below 88.1. Did I get an "illegal" transmitter years ago or has something changed?
