Hi does your vci turns on at all? look at all the led lights on the vci, and tell us which are on or off. its the Bluetooth enable on your tablet? have you downloaded apps from amazon or google play recently, if yes uninstall them all and try again. if no connection can be made thru the usb cable you will not be able to update the vci. I will say either your vci went out or your tablet has hardware issues or software corrupted. also am assuming your using the vci that came with your tablet and not a different one since it can only be paired once. another test you can do is connect your vci thru the usb cable to a pc/laptop see if windows recognizes your vci and you should be prompted to install the driver software. good luck buddy hope you get it going.
