Took me about 30 minutes to install from start to finish. Added Bluetooth to my daughter's 2005 Acura MDX. I slipped the mic through the dash and stuck it in the air vent so it wouldn't get in the way. The box fits easily in the glove compartment. I highly recommend using a splitter to keep the XM running, and surrounding the wires on each connector with ferrite magnets to avoid shorts or oscillator noise. Bluetooth works exactly as expected, she didn't call the speakerphone. exactly what we wanted.
