Bluetooth communication

When Bluetooth devices are connected between Android devices,(android - android)
do you know how to receive incoming SMS message from other device via bluetooth?
for example, i have android phone and android navigation. when two device are connected ( bluetooth),
if phone receive SMS message, is it possible that navigation also receive incoming message from android phone? (like smart watch using SAP)
if you have some solution, please let me know.

There is Message Access Profile (MAP) in Bluetooth stack. It must be supported by both devices. Usually it is used by communication with car system. But actually it is matter of software on the phone. MAP is supported by iPhone.
