Abstract

A customer relationship management (CRM) method using IBOC-radio signals is provided. A message in the radio signal is parsed to obtain a key. The key is compared to a plurality of stored keys. When the received key matches a stored key, a data structure associated with the message is outputted. A device comprising a lookup table with a plurality of stored keys, a tuner unit that receives a CRM in an IBOC signal, and a controller in electrical communication with the lookup table and tuner is provided. The controller comprises (i) instructions for comparing a key in the CRM to one or more stored keys in the plurality of stored keys and (ii) instructions for permitting the display of a display text associated with the received key when there is a match between the received key and a key in the plurality of stored keys.
