The unit often becomes unresponsive. The sound source continues playing, but the screen either goes blank or remains unresponsive. The buttons also stops having an effect. Changing the volume makes a beep sound but has no effect on the volume under these circumstances.

The only way to recover the unit is to switch the car off and back on again.  

Any advice?

Is there a later build available for this unit?

Hi,

please reset the unit by pressing the RST icon to see if it can be solved, if no, then it might be backlight issue.

Best Regards.

The reset button obviously works, however the screen should not freeze in the first place. How can I determine what the root cause is?

You also did not respond to my request for the latest build.

Hi,

we have the upgrade firmware for this unit, i would suggest you do not upgrade it if nothing serious with your unit, or it may somehow damage it.

Best Regards.
