Abstract
A wireless connection apparatus which scans radio frequency bands for local quiet unused, vacant, or unassigned frequencies which the apparatus can use, on a temporary basis, to establish a link for communicating between a portable multimedia device and a nearby RBDS/RDS configured receiver or source. The apparatus does not interfere with or utilize frequencies actively in use by an assigned user.
