I have a Seat Ibiza 1.4 TDI (2004), and recently I have installed a Seat MFD radio navigation version D, but unfortunately it is not working properly.

The main problem is, if I stay more than 10 days without running the car, the battery loses all charge (It is impossible to open doors, starting the engine, etc).

I have already uninstalled the radio and confirmed that the problem is in fact from it.

So, could anyone help me to solve this problem?
