Why factory fitted Sat Nav?

Because of its integration with the ICE (you don't have to turn down the music to hear the sat nav)
Because of its large easily readable screen
Because its integrated into the driving position and dashboard illumination
Because it improves the look of your car's interior and dashboard
Because a big sucker and tom-tom or smartphone hanging off the windscreen looks cheap and tacky
Because it also contains a hard drive for music and BMW connect for downloading maps and information
Because it relieves driving stress and makes finding places far easier
Because it rarely loses the satellite signal unlike a smartphone
Because of its integration with your smart phone
Because it can be integrated with Voice Command, making operation while driving much easier and less distracting
Because it can have split screen real time map with large scale (lot's of detail) as well as arrow directions to help navigate tricky motorway interchanges, town centres etc.
Because it integrates traffic information to avoid jams
Because of its emergency situation functionality (calling emergency services with car's position)
Because the large screen coming with the SatNav is used for a host of other apps, including Internet, Smart Phone Integration, OBC etc
Because a used BMW w/o Satnav is a hard sell and dealers will suck their teeth and make lowball trade-in offers, or create more negative equity when settling finance
Because if financed, it doesn't cost £2000, it costs £35 times the number of months you keep the car
Because if not financed it doesn't cost £2000.....it costs £2000 minus whatever the residual percentage
Because a modern dashboard w/o SatNav screams 'underspec'd', regardless of the other options fitted
Because you can't forget it or leave it somewhere
Because you won't get a ticket for operating your car whilst driving
