1) When i turn on every time it ask to register an SD card for communication with the PC, you answer yes - impossible, no - it will ask again the next time you turn it on.
Solution: Check on the side of your sd card, there is a small button lock/unlock the card. Move it UP so that SD card is UNLOCKED so that the system can register on the sd card. Try after that and press YES when the stereo asks you to register card.
2) When you turn on, it always offers the initial setting or something like that. In this case, the adjustment button is not active (in the settings menu also not active), the button is configured later. And so, too, every time. Bothers.
Solution: Press menu so that map shows on your stereo. Go to settings and find INITIALISATION. Uncheck the choice which says "show setup at start", the option will not show again.
3) System settings such as the button backlight color, volume, or mute buttons are not saved.
Solution: When you change these settings dont press "Back", press SAVE, normally this button is at the bottom right.
4) Well, the last - someone can know the exact sequence of actions for establishing a connection using bluetooth, I only get a tambourine. I'm constantly on the phone, I want to get into the car loudly
Solution: You have to "register" your phone. Go to menu, settings, Bluetooth settings and press register. Once the stereo finds the phone insert the code, normally 1111 on your phone and pair. Keep the bluetooth on your phone ON. Restart stereo and give it 10-15 seconds.If you have music on your phone, press the Bluetooth audio option when in AV, and press the arrow so that music plays. It will e music from your phone.
