My wife just accepted a job as a home care nurse. She is paid by the amount of people she sees so the faster she gets done the more $ per hour she makes. She is hoping to avoid being lost as much as possible. She is looking for a basic GPS that can be programmed the night before with all her stops. The stops must be completed in order. Congestion avoidance is also a priority. Any suggestion? We live in Canada in the Vancouver area if that matters.
