to your fault on the bose system i cant say antything, i still waiting for my car
Hi Malik & welcome in the forum, 
unfortunately we do not have good news for you. As Maverick already has stated, the Coming / Leaving Home Feature only works, if the lights control button is NOT in Auto mode And/Or when the driver pulls the direction-indicator control directly …
For all drivers used to run the lights with auto mode, that feature is completely useless. We already have discussed that strange implementation approach from Mazda and lots of us already have touched base with the dealers, but so far no fix for that. One of the few things, the engineers could have done better... 
Does somebody have the same problem that the bose system gives music from the right speakers and sometimes from te left speakers?
I had the same issue with my car just when I got it (no BOSE unfortunately)
Found that the issue was that the GPS was programmed to a destination, so it should give voice directions once in a while.
Because the volume for the GPS voice was set to "0" nothing is heard, but anyway the normal sound is reduced for the duration of the voice message. Not sure if the explanation made sense?
