There’s been some debate as to whether the starter battery is on charge when on hook up. If it is, the amount of charge is minimal. I don’t risk using the radio for long periods when not driving , anyway it’s a pain in the arse as it turns off after 30 minutes.We’ve finally treated our Cali to weekend of charge on EHU. I gather this also charges the starter battery. Does this mean you can safely use the car stereo for longer without the risk of a flat battery? I didn’t dare risk this!
According to VW it doesn't, but according to my voltmeter it will trickle charge the engine battery if the Leisure Batteries are full. Whether by design or a fault I dont know, but it works on mine.We’ve finally treated our Cali to weekend of charge on EHU. I gather this also charges the starter battery.

If the leisure batteries are fully charged, then the charger splits to the starter battery, but indeed, I would not be sure if you won't drain that battery if you are listening too long.There’s been some debate as to whether the starter battery is on charge when on hook up.

How did you change the duration?If the leisure batteries are fully charged, then the charger splits to the starter battery, but indeed, I would not be sure if you won't drain that battery if you are listening too long.
As for the 30 minutes, on my RCD310 I managed to change the on duration to 199 minutes.
