Playing a bit more this morning.
If I clear out the MP3 playlist from my radio presets (ie, delete all the entries in the preset list) then add a couple of stations, if I toggle in and out of "LOCAL" mode, the presets all disappear.
And I also noticed a #4 to add to the list.
If I'm tuned to FM, and directly key in an AM frequency, the AM station is tuned in, but the display still says "FM".
Anyone have any suggestions for any of these issues?
