I accidentally started the update on my head unit. and now it wont stop trying to update unless i turn the car off and turn it back on. but when i turn it back on the radio wont turn on or nothing so i have to uninstall the receiver, and unplug the wiring harness, am/fm antenna, RCAs and the mic plug. the reinstall it and plug everything back in. when i do that, it comes back on but it goes straight back to trying to update. i cant get out of it? ive tried to reset it and that doesnt work.. can anyone please help me out here? i figured if i got the update off of alpine.com and updated it, it would go away but theres not a update for the USA. please help.
