I have the OEM radio in my 2014 Sienna LE. Started having some issues recently.
- Day before yesterday started van, and the VFD display was blank, but all the buttons were backlit.
- After a minute or two it came on and radio worked normally.
- Yesterday, driving to work, on startup, the display was blank, and the backlight for the buttons was flashing on and off.
- After a few minutes the display came on and it started working
- Later in the drive, the screen stayed on, but it started alternating the backlight of the display and buttons between dim (headlights on, which they were) and bright (headlights off)
- Today, the screen didn't was blank
- Oddly, it connected to my phone and played audio just fine still
- None of the controls (power, volume, skip) on the radio worked, but the steering wheel volume and skip controls did work.
- Display came on later, but none of the buttons on the radio continued working
