Official summary

Some vehicles may exhibit a Connectivity Master Unit (CMU), a BLUETOOTHà ® hands-free unit or text messaging related concerns. To improve the handling of BLUETOOTHà ® hands-free and/or text messaging customer concerns, Mazda created a special service and parts exchange program as of February 2010.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
