RNS-E on with car, using SAT tuner or TV tuner: ~4 amps

RNS-E on with car, using radio or mp3: ~3 amps

RNS-E off with car, first minute or so (fans still on, amp still on): ~2 amps

RNS-E off with car, after no more than 5 minutes (fans off, amp off): ~6 milliamps

If your multimeter is still reading 2 amps across the radio fuse after 10 minutes then it is causing a battery drain. This is most likely due to the amp never turning off. Make sure that your AMP turn on wire is connected to pin D13 of the RNS-E (NOT pin D16).

How do you measure this?
I actually tried as well this weekend, but had problems finding anything to stick into the fuse contacts. Are there special fuses that let you hook up a Multimeter? Also, on my A3, there are 3 different fuses that could be considered:

- one labelled "Navigation/Homelink/..." (inside)
- one labelled "Audio Amplifier" (engine compartment)
- ond labelled "Radio" (engine compartment)
