I bought this unit last month and have it connected to my 1984 Aspencade, paired to my 10S headset. The CB part works great, except I get an echo through the headset when I talk. Haven't figured out how to clear that up - the instructions are not very clear. When I have my Satellite Radio connected into the Au input, I cannot hear the CB conversation - it gets drowned out. I now play the Satellite Radio through the cassette adapter in the on board stereo and it works great. I also seem to lose the connection when using my cell phone. Tapping the red button seems to bring it back on, but is a bit of a pain.
I have also had issues with my passenger Bluetooth connection - it drops out on its own a lot when I am connected to the Freewire. If I turn off the Freewire, my 10S sets work flawlessly. Maybe a limit to the number of devices my 10S can connect to?
