I OWN A 13 INCH ANDROID 13 CAR PLAYER PAIRED WITH HIWORLD CAN BUS ADAPTER. INITIALLY IT WORKED FINE. I MADE A MISTAKE TO DO ONLINE UPGRADE OF CAN BUS FIRMWARE AND THE REVERSE RADAR STOPPED SHOWING. ALL OTHER FUNCTIONS WORK AS USUAL. ANYBODY CAN SUGGEST OLD FIRMWARE DOWNLOAD LINK SO I COULD MANUALLY RESTORE THE RADAR FUNCTION?
I OWN INDIAN MADE TATA NEXON CAR
