We went on trip to an unfamiliar area. Of course we used the car navigation system. Wall's
But for the return journey the "Nav" screen on the car failed. This was a surprise as the car is about 11 months old.
Luckily the return journey was well signed as we were heading back to the Big Smoke.We also have a map book (2013 edition ) for our region sitting in one of the car seat pockets and our mobile phones ( 2 off )have map functions.
So three back-up in total.
And back at home there are two Tom-tom navigation devices. One is no longer supported and its suction cup device is broken but otherwise it still works. I trying to think of a use for it.
Reviewing it all having 3 systems dependant on GPS and the fourth system seven years out of date is not ideal. I will get updated maps for Queensland and New South Wales.
Update - and Mazda replaced the faulty unit in the car- no worries.
