Is your VBOX compatible with the new firmware?
The new firmware can be installed on v3, v4 and v5 variants of the VBOX 3i. VBOX v3 hardware variants started shipping at serial number 32390 (Jan 2014), but may be available on older units if they have been upgraded to V3 'IMU04 ready'. Look for the silver 'IMU04 ready' sticker if you are unsure.
If you have an earlier model, you can trade it in and get a significant discount when you upgrade to the latest generation VBOX 3i (v5), which will come with the new firmware pre-installed.
