Hello,

today I came across a lot of discussions that Bluetooth module might be the reason of annoying "First Track" issue, and that dealers change them by warranty in some countries for some car models.
At least it was that way for CX-5.

Now I'm curious if this is also working for Mazda 3 BM.
Which BT modules have the problem and which don't?
Is it a HW issue of BT module, or is it a SW issue of those modules?

Where is BT module located in our cars physically?

There's a TSB #09-008 /15 related to this issue, as far as I understand. At least in USA. Not sure about EU.

Any info related to 3 BM and this issue would be appreciated.
