A hand-held programmer that is adapted to interface with a variety of vehicular accessories is disclosed. The device allows a user to preselect the desired settings for a particular accessory and then program that accessory with the push of a single button. The programmer also provides for an operable connection to a manufacturer's technical support computer via the Internet whereby software updates may be downloaded to the vehicular accessory and data for remote diagnostic troubleshooting may be exchanged between the manufacturer and the installer.
