What did you test...? With mine the problem is there is a small metal pad at the back of the power connector that the base of the connector should touch against when there is no plug inserted... This allows the empeg to detect when the plug is not inserted and therefore when it is in the car... In my case the base of the connector has stopped springing back high enough to touch the pad at the back and so the empeg sees the connection as always open and assumes this means a plug is inserted and so we must be in the house... My physical hack was to use a piece of metal to bridge the gap between the base of the connector and the pad when I am in the car... it's horrible but it works... I am still looking for a software solution... current thoughts are to have it default to in car behaviour (quieter) and allow the holding down of a button when booting to signify in house behaviour as it is also easier to reboot in the house than in the car if you forget to hold the button down...

I'll let you know if I get anywhere...
