Connecting to a Different Phone
To connect to a different cell phone, the Bluetooth system looks for the next available cell phone in the order in which all available cell phones were paired. Depending on which cell phone you want to connect to, you may have to use this command several times.
1. Press and hold 
for
two seconds. For vehicles
with a navigation system say
“Hands Free” after the tone.
2. Say “Bluetooth.” 3. Say “Change phone.” . If another phone is found, the response will be “<Phone name> is now connected.” . If another phone is not found, the original phone remains connected.
