Such innovations in the Astra include three-dimensional instruments and a 6.5 inch monitor for the information display. An all-new 'infotainment' system will be available in the new Astra, stretching from a top quality audio unit with MP3 function to a digital radio with CD quality and a six-CD changer integrated into the front panel. There are new steering wheel remote controls with buttons and turn-press wheels similar to those on a computer mouse for safe and comfortable selection of functions.
