why is it that the navigation system on the Leaf doesn't update<i have just found out that if i want to update mine it will cost me another £360.20 for a new sim card (coded for my car.) so at the moment all i get when i try to find charge point its about 6 years out of date, last week was the first time i had taken it on a long drive where i needed to charge up on route, i was sat on a charge point charging and my navigation system said the nearest charge point was 20 miler away.
