Older sports cars are great for hitting the open road, but let's face it, they lack the bells and whistles of modern automobiles. Porsche is looking to help, though, with a new version of its Radio Navigation System for those older vehicles. On top of turn-by-turn directions, the Bluetooth unit sorts hands-free calls with ports for playing tunes from an SD card, iPod, USB stick or via an auxiliary cable. So if you have a Porsche 911 up to type 993, or a 4- or 8-cylinder that dates back to 1965, you're in luck. Best of all, this new unit sports the overall look of those classic interiors, rather than a modern faceplate from the likes of Pioneer or Alpine. The automaker has offered to outfit older cars with navigation systems before, but this more robust upgrade costs €1,184 (around $1,342). Unfortunately, US pricing and availability hasn't been announced just yet.
