Is there any reason why the in-car systems are so much more expensive than the portable ones?
I understand they have additional inputs from the ECU, speedometer and sensors etc., but it seems they generally have less POI, features, less easily customisable and possibly less raw computing power compared to the portable models. Not to mention, they're larger so the cost is unlikely to be due to the need for miniturisation.
Just trying to figure out what exactly it is that makes them cost 6+ times more (depending where you get it.) Anyone know?
