Long story short(-ish): the owners handbook states that F68 is a 5A "spare" (at least for an 06 V8V, don't know about other models/years). Based on that info, I used that fuse to replace another one that had blown. Some time later, I discovered the Bluetooth system had stopped working (you can guess where this is going). There was no reference to a Bluetooth fuse in the handbook, so I emailed AM. The answer came back, yes, you guessed it, F68 is for the Bluetooth system. So Bluetooth owners, take up your handbook and cross-out "spare" for cabin fuse F68, and write "Bluetooth". I wonder what other "spare" fuses are in fact used for some optional system or other?!

 

Who did you email?
