I expect this has been covered elsewhere, but has anybody figured out how to extend the time before the Meridian audio system fitted to the MY13 FL2 powers off. Mine powers down after 10 minutes when engine switched off which is a pain when you're waiting to pick someone up and all you want to do is listen to the radio for 20 mins or so while you wait. Sitting with the engine running to listen to the Archers isn't exactly eco friendly.
