Abstract: A mobile radio receiver for a vehicle includes a tuner front-end section, an inter-vehicle communication port, and a data processing unit. The data processing unit is operably connected with the tuner front-end section and with the inter-vehicle communication port. The data processing unit has at least two pre-determined relationship data sets. In use, the inter-vehicle communication port receives a tuner front-end section parameter data pointer. The pre-determined relationship data sets are used to determine a set of tuner front-end section parameters based on the tuner front-end section parameter data pointer. The mobile radio receiver provides an operational mode, a parameter reception mode, a tuner parameter adjustment mode, and a tuner parameter application mode.
