r1000

Hello all, I've purchased a used 2004 R50 SE. The dealer told me about the radio "issue"! However, I don't think it's a radio issue as it turns on and tunes to stations and pushes sounds to the tweeter. Or maybe it is?? I've read in other general forums not specific to Nissan that maybe the factory amp. Do these even have amps between radio and speakers? If so... where? My commute is long.. so I neeeed a radio Also, my shifter area is completely black...no lights at all!!! Hoping it's just the bulb and if so, how do I get to it?
