Bob, I have used the SST model in my Plus 2 for several years. I did a pretty thorough write up in the thread below. The summary comment remains the same; a good but not great radio that solves the Plus 2 mounting depth problem well. It is still working without issue, and love that it keeps the station settings with the battery disconnected for storage. Very happy with it.

Can't recall if I posted the story of the radio going haunted and changing stations at will. It was caused by my wife placing her phone on top of the remote stored in the glovebox!
