I was taking my first trip across the country and I wanted to be prepared for anything. I got my car a tune-up and also purchsed new tires. I also stocked my car up with plenty of food and stuff to drink,non alcoholic. One other thing that I decided to purchase was a portable gps unit. I looked online to see who had the best price and features. I didn’t realise the prices had come down so much. I found one unit i really liked, it was a garmin nuvi 350 and it seemed to have all the features that I wanted to have.
