Personally I would just buy the Way finder licensee its only $45 a year if you buy it 3 years at a time. The fact that it only last 3 years for the subscription is fine with me because I doubt I will even have the n810 for 3 years in that time there will be similar devices 10x faster for less money. Even if you have the device for 3 years I am sure by that time it will be alot cheaper to resubscrib.
