Although it’s an older car, your mom’s 2007 Chrysler Aspen might have Bluetooth. It was an available feature for the model back in 2007 and would have cost the original buyer about $350 extra.
If the vehicle does have Bluetooth, its location and controls are a little awkward and might not be where you expected them. They’ll be located on the rearview mirror. The early UConnect system available on the Aspen came as a package deal with an auto-dimming rearview mirror, so that’s where they stuck the UConnect controls.
If you find your car has an auto-dimming rearview mirror, you can turn on the UConnect system with the mirror’s controls and pair your device.
