1. A method for operating a navigation device that also uses two tuners to receive Traffic Message Channel (TMC) data for ascertaining an optimum travel route, comprising:
- comparing, by a computer processor, first TMC data to second TMC data, wherein the second TMC data is of a first one of the two tuners and the first TMC data is found in a first search by a second one of the two tuners; and
based on a result of the comparing, searching, by the second tuner, for a station with third TMC data.

Abstract
In order to provide a method for operating a navigation device, which also receives TMC data using two tuners for ascertaining an optimum travel route, using which an optimal travel route is ascertainable using the largest amount of TMC data possible, after a first search by the second tuner, the TMC data found are compared with those of the first tuner and to use the second tuner for searching for another transmitter having other TMC data. Furthermore, a navigation device of an appropriate design is provided.
