MiVue Smartbox III

Changes of Smartbox III vs Smartbox II

  • Slightly bigger box, with no lateral fix-screw ears/holes
  • There seems to be both 90 degree corner mini-usb and straight usb end connector versions
  • Fully compatible with Mio MiVue 8xx series and C545 HDR, C580 HDR GPS, C588t Dual and 798 Dual Pro cameras. 
  • In the MiVue 846 and 848 models, the mini-USB plug can only be connected directly to the camera module. It is not possible to plug it directly into the active mounting bracket. 
  • The minimum power cut-off voltage has been raised to 12V (adapted to the latest car models).
  • Internal capacitor that maintains the power supply for approx. 3 minutes after the voltage drops below 12V.

MiVue Smartbox I/II

Mitac CA-0521MV-05 seems to correspond to Mio Smartbox (I) or Mio Smartbox II, but also found in reference photos of Smartbox I or unspecified. There are inconsistencies between the outside label and the inside PCB inscriptions. Both 2014 and 2016 versions use “Mitac CA-0521MV-05” label on the outside, while inside PCB shows “Mitac CA-0521MV-05” on 2014 version, and “CA-0521MV-06” on the 2016 version.
