I have stuck non-slip matting strips to the bottom and back edge and it is now wedged into the corner of the dasha nd window, in the same place as the pic above.
I have also hard wired a 3 way cig socket into the little area in the left of the drivers dash, over the clutch pedal area and then have got phone charger and TomTom Go charger in here and hard wired so TomTom Go has power all the time.
I have also used the same cig socket for my Snooper S4 which sits to the left of TT Go. I have even wired in my Ipod 40GB 4g too ------ yes I like my gadgets.
It takes me 10 mins to commision and decommision the gadgets when I get in and out of the car.....but at least they don't get seen or stolen this way.
Pottsy - What phone do you have? That photo is really quite clear.
