If you try the VIN decoder television indicated and if you can find option code 386 from the list, you would have full UHI phone kit, if it lists 273, that would be just the prewiring (telephone pre-installation, no cradle, no control box but wiring, antenna etc.).
But if it is a 2001 car, it cannot have UHI from the factory. If it does have a phone kit, you would see a phone cradle somewhere.
