Hi! It's my first topic on this forrum, so I'm very sorry if somebody has already asked about this. Yesterday I've updated my Pioneer Avic F500BT (only maps (My Flash Disk), but no system). New maps work amazing, but there is one problem - I dont have lector. I can hear pause in the radio before communicate, but there is only pause and noise. Any ideas? Thank you very much! Kind regards!
