Digital TV optional: DVB-T, ISDB-T are optional. Digital TV has a TV Tuner outside.
NOTE: After installation, if there's no sound, your car should be with fiber optic amplifier, then you need to connect our long speakers cable(already in the package) with your speakers directly in the trunk and by-pass the existing amplifier, so your fiber optic amplifier will not work anymore, but our unit has 4x45w amplifier built-in.
