(1) v3a5 is safe, if v3a3 works.

(2) The crossfading and other bugs behave MUCH better (for me) in v3a5 than in v3a3.

(3) If your car voltage supply drops below about 10VDC, with *any* player software installed, then the audio will be muted (but not stopped), the player state will be written to flash, and the display will be blanked. If the voltage later ramps up above about 10VDC again, then the display will be unblanked and the audio will be unmuted. Design intent. Fix your power supply!

Cheers
