I recently had my Phatbox completely stop working! I mean no lights or anything. I come to find out that the actual Phatbox "needs" to be grounded/mounted. So I bought the Audi mounting brackets and everything is working again.
If you have a RNS-E and a Phatbox, get some machine screws and mount the Phatbox to the car! Its the only way mine would work while connected to the RNS-E!
