My only real safety concern is this. Do you have enough space between the computer and handle bars to allow a full "lock to lock" turn? Looks tight to me.
The Tablet PC is mounted to the handlebars, not the tank. It swings with the rotation of the bars.
A lot of people think the GW Navi is lacking and in some respects it is, but I have found it more than adequate to tell me just where I am lost at.
I would like the NAVI more if there was a wired, or wireless full QWERTY keyboard connection to enter DATA. This hunt-n-peck entering of addresses is driving me crazy. There is more that it CANNOT do, than what it CAN do.
After you use something like
Microsoft Streets & Trips, you'll understand how the NAVI leaves you wanting. This program, along with the screen that is more than four times that of the NAVI, gives me FAR more capabilities for navigation.
I also think that the safety function built into it whereas you cannot manipulate the functions when moving is a good thing.
I think it is silly. Why don't they install a device in a car that forces you to pull over when you are about to sneeze?
You close your eyes when you sneeze, and that is involuntary. You cannot decide WHEN you will sneeze, even when you are driving through an intersection or approaching a line of school children crossing a road, but you CAN decide when you will, and when you WILL NOT glance at the PC screen. All of these attempts at regulating the attitude of the people NEVER works. Prohibition proved that. The "feel good" hands-free requirement of cell phones for drivers did not solve a problem. It only converted it into a texting-while-driving problem. Now they're talking about making cell phones inoperable while moving. GREAT PLAN! That will really help the teenage girl who is being stalked by a car full of horny gang bangers, or the battered wife who is fleeing from her drunken abusive husband. She will try to call 9-1-1 and the phone will say,
please pull over and stop your car to make this call. Another STUPID "feel good" law created by the brain dead liberals.
Since your bike goes where your eyes go, I don't want to be looking down to change scales, or make corrections. At my age, my reaction time is not what it used to be and I need all the help I can get.
I will not be making any adjustments to the screen while I am riding. It is a
visual reference only, just like the speedometer, the tachometer, the temperature gauge, the fuel gauge, the radio station, and the rear view mirrors, each of which takes your eyes off of the road momentarily.
Don't' get me wrong, this is just my opinion and I have to admit that your set up is clever and looks very functional. It's just not my cup of tea but I admire your attempt at having a tank mounted device that does it all. Other than what I have stated above, and the price, it's a cool set-up.

Already covered. NOT tank mounted.
The thing I like most is, when I want to use the map, I can pull over and grab a digitizer pen. Click here, drag the screen to the left or right to see what is ahead, do a radar search for a gas station or a place to eat, zoom in or out, etc. When I plot a route and it appears as a blue translucent line over the road I am traveling, I can grab that line at any point and drag it over to another road and the computer will instantly recalculate the route. If I am stuck in traffic, I can drag the path to a side road that looks good, and in a matter of less than two seconds,the computer has completely routed me around the obstruction. With the Internet connection, I can overlay traffic congestion patterns in red,yellow and green lines, and avoid traffic snarls. There is SO MUCH more that this program can do, that it makes the NAVI unit virtually meaningless.
The PC also lets me keep an EXCEL spreadsheet handy and open. Stop for gas, enter the DATA. Stop for lunch, enter the expenses. Riding and see something you want to check out later, a quick stop to put a pushpin on the map for later reference. Switch screens for live weather maps. Text messaging with a keyboard or by using voice recognition. The list goes on.
