The telephone system comprises a signal conditioning module for reducing feedback and amplifying signals received from a telephone handset, a vehicle entertainment system for amplifying and broadcasting incoming telephone calls and a pair of releasable interfaces. One of the interfaces releasably couples the signal conditioning module to a receiver portion of the handset. The second interface releasably couples an output of the signal conditioning module to a tape player of the vehicle entertainment system. In a second aspect of the telephone system, the signal conditioning module is releasably coupled to the vehicle entertainment system by a low power transmitter which is in series with the output of the signal conditioning module and an RF stage of a radio of the vehicle entertainment system. In a third aspect of the invention, the signal conditioning module is coupled to the vehicle entertainment system by a low power transmitter and a shielded cable having one end portion releasably connected to the signal conditioning module and an opposite end portion connected to an antenna socket of a radio of the vehicle entertainment system.
