have a Bose Lifestyle 20 system which is built into a 10 year old motorhome I obtained recently. About a month ago the audio went out in the motorhome.I beleive I have narrowed the issue down to either the Lifesyle Music Center or the associated "Built-invisible" unit. Both elements are getting power so my question is this: Are there any fuses internal to either the music center or the "Built-invisible" unit and If so where are they located? I have attached a picture of the "Built-invisible" unit.
