Porsche Communication Management features a built-in CD drive (for both audio and navigation CDs), a high-resolution 5.8-inch colour display with 16:9 screen ratio, and a satellite navigation module. The GPS system uses an integrated antenna to establish your position before calculating the route to your chosen destination. It can also provide a range of alternative routes using the TMC (Traffic Message Channel) service currently available in some countries. System menus are easily navigable using a single multi-function rotary control. The integrated audio system features RDS two-tuner frequency diversity as well as 20 FM and 20 MW presets. Navigation CDs included.
