Mounted tablet, maps, diagnostic and use?

Maybe I'm missing something, maybe you & I have a different idea of what navigation entails, but, to my mind, the need to simultaneously drive AND navigate is likely to be a frequent occurrence for many of us - I know it has for me - I don't always have the luxury of a second person in the car with me.

In the era of paper maps, I would spend the evening prior to my trip determining my route and listing the turns on a notepad which would then by clipped to the folded map and placed on the passenger seat - a quick glance would let me know my next turn would be, let's say, a left onto ABC street in roughly two miles - making a wrong turn would require finding a place to pull off the street and spend several minutes "re-routing".

Paper maps left me with a fear of "detour" signs that stayed with me for decades.

One of my memories of driving to Miami International Airport, has me needing to make a left turn exactly where I had turned the week before, only this time, there's now a concrete barrier preventing me from doing so - I had to find a parking lot and get out my laptop based GPS which of course had a map that didn't know about said concrete barrier, just to get to the rental car return on the other side of the street.

Even in the city I grew up in, and I can draw street maps from memory, navigation decisions need to be made as to which street to use to get from point A to point B, don't drive on Carifesta Ave at 8:00 am on a weekday because of the school traffic, take the "sea wall" road instead.

To me, navigation is a part of life, inseparable from driving, inseparable even from walking - did you know Google maps will help you navigate to a given store in a shopping mall?

I use Google maps on a regular basis and I find them extremely useful. I am also blessed with the homing instincts of a pigeon and that is a blessing.
At this point I feel that an explanation of how I navigate from A to B, without the assistance of a navigator, will clear up any misconceptions of how I do it. I decide on a route. This is usually based on previous knowledge and I can commit to memory considerable distances without needing recourse to a map. Best so far is Birmingham to Inverness, a distance of 460 miles. Yes it was mainly motorway but there are junctions on route. If I need to check a map I find a suitable place to stop and then check. Yes , I have seen people looking at maps whilst driving and I wonder how they have managed to survive for so long and they are prime targets for the police and a "driving without due care" summons and yes, I have seen drivers with either a hand held mobile or an ear mounted device apparently talking to their alter egos and I have muttered under my breath "never a copper when you need one". My father in law is 25 years younger than me ( don't ask ) yet a minor detour had him totally lost in Redditch and it required a rescue mission to find him and deliver him safely into the bosom of his family. Such is life.
