does your current RES 130 have a phone button ?
Most 2009 Dodge Rams with the RES 130 did not have a phone button
A few came with the phone button, they were called RESs 130
I suggest that if you don't have a microphone, buy a normal microphone that will work with the radio & install it either on the "A" Pillar almost against the Windshield, or above your right eye & forward a few inches, against the overhead console & roof liner.
( the reasoning for those two spots, is the stock Ram rear view mirror microphones are
not noise cancelling & they pick up the noise from the Blower Fan in the HVAC system & they also catch the cross winds if your windows are cracked open.
Ram realized this, just read the owners manual
It reads close the windows & turn down the fan
to use the microphone
There are videos on how to upgrade the radio from the RES 130 up to the RER 730 or RHB 730
here is an explanation, no video, 2009 - 2012 are the same
It does not upgrade with an OEM radio though
