Yes ive done my research! But i cant find anyone who posted a similiar situation so makin a new thread. So i was reading about navi fixes and solutions, my navi is constantly saying "please check disc" when i turn the car on. It wont change from that. Thats all it does. Ive tried taking the hard drive out and cleaning the "lens". But it still gives me the same message. Disconnected from battery for seconds... Still same message...replaced with a new disc.,.still same message... No matter how many times i inspect my disc... This stupid message wont go away lol...i dont have $$ to send it out etc..n id prefer diy anyways. Help please...i have navi code if that means anything...
