I brought my new 31SS home today. Really like it! The nav system worked fine for me so far, but, I was on roads I was familiar with. Time will tell how it does on unfamiliar roads. Since I already have lifetime map updates on my Nuvi, I will probably use it in the MH if I find the new nav system is less accurate or the maps get outdated.
