If you are the owner of a Porsche which doesn't have factory navigation system, why not upgrade the radio head unit with a after market Porsche navigation? The porsche navigation system has many functions built-in like DVD player, GPS navigation, iPod, USB, radio FM/AM, MP3 player, bluetooth, etc. It's so cool that you have a Porsche, but it's much cooler that your dashboard is with a individulistic after market porsche navigation system.
