I think both of them. When accuracy is poor, lock to the road feature fails to lock to current road. I had it once. When I turned on my Nuvi with active route on screen appeared jumping car. The car icon was on the road nearby actual road and car icon was jumping. After a while accuracy increased, and Nuvi locked to the actual road. Car jumping gone.
