What do you do for a speaker?
Are you running it through the HK radio?
I use the "audio out" jack on the back of the unit - through the fairing and connected to the back of my "non HK" radio, using the "how to hook up a rear auxiliary jack etc".
Switch the radio to AUX and I have my XM.
I know that if you are using the 12volt speaker combo that the speaker is disabled if you have a plug in the audio out jack.
Route commands will go through the audio out jack,
music cuts - route command given - music plays.The audio for the voice route is way too loud and not adjustable separate from the XM output.
The Audio out jack has two setting "headphone" and “line out". With the headphone you can adjust the overall volume through the menu. The audio output is fixed with the "line out".
One thing I haven't tried yet is to see if the audio output on the "motorcycle cable" is muted when using the "line out". I will try that this weekend.
The problem with the motorcycle cable is that the audio jack is only a few inches long and right next to the power plug.
I think the motorcycle cable is nothing more then a glorified 12V cable (which does have mono audio output).
In my truck I have the GPS wired using that cable, with the audio output going to a speaker lying under my console. Works well.
The route commands I have found to be of little use on the bike. Actually, when listening to music and having the commands come blaring through is annoying. Especially when you have a lot of frequent "turns" coming up - think highways with a lot of roads converging.
I'd like the power on constantly as well to avoid shutdown.
Using the “hot” switched supply lets me keep it powered up when doing a less then 1 hour stop or shutting it down simply by flipping the switch.
Remember, we have small batteries (the bike) and if you are using the XM puck you are using 2-3 times the current. Ever feel how warm the puck gets?
