2010 Chevy Impala LT
Just inherited car.

Onstar in car but subscription not purchased.
"Bluetooth" not recognized when "Ready" given.
Will not link my Samsung 4 or wife's Samsung 5 cell phone.
Bluetooth on both phones work with 3rd party "cheap" bluetooth device.
Last 8 digits of VIN A1112452

Can anyone help as I have read other posts on bluetooth without clear solution?

Original purchase sheet does not say Onstar or Bluetooth.
Help -thanks.
