Cultus VXL's audio head unit (LCD - factory installed) has frozen a couple of times over the past one year. Basically, the buttons remains clickable but nothing happens. 1st time, the dealership just disconnected and re-connected the battery and it worked fine again. 2nd time, the car remained parked for a couple of days after the issue came up and now the battery is dead. No other lights etc were left on.
Anyone else faced this issue?
