I don't really know too much about car audio, but I'm looking for an indash GPS system that can log business miles, it also needs to function as a computer screen (i'd like to have a media center PC eventually in the car) as well as a sat. radio tuner. Does such a thing even exist? The closest I've come is the Panasonic AVIC-N2, it's pricey and I'd be concerned about it getting stolen, but I could leave the GPS running while I'm out on business and just log the mileage that way. Also, does anyone who owns or is knowledgable have any opinion on this unit? Are there other manufacturers out there that offer a better device?
