We arrived to San Diego at 7 pm after 21 hours of travelling. Last 3 hours was drive in a rented car from Los Angeles to San Diego, during which we tried to use Lowrance AirMap 1000 as a car navigation system. Now I can definitely confirm that car navigation is not the best application for AirMap 1000
BTW. The car we rented is convertible, I have never driven convertible car before (it is not very practical in Poland), but here in California it is just perfect, I love it!
