We nuzten the Grundig 22 VLE 521 SG on satellite channels in the motor home, a very clear HD picture and good sound, the speakers are located on the front panel. When delivering a 220 volt power supply is being connected to 12 volts on the device. A 12 V DC coiled cable with plug-in adapter, still has to be bought separately. Would be perfect can be used for campers with the matching 12 volt cable because in the description is that this TV.
