For as much as that factory Nav costs, and for each update you have to buy, you could have many Nuvi 660s with lifetime updates. I use mine in my truck, car and on two of my bikes..... It always there as well. If it ever got stolen I might turn it in to insurance and get another off eBay for what the cost of an annual update is for a factory installed Nav unit.Never need to worry about factory Nav being stolen & it's always there:act006:
