Just installed an old (2nd hand) GPS Garmin streetpilot into the car.  

but it’s soooo cool, it’s got an audio function to tell you when to turn, how much distance left till turn, estimated TOA, speed travelling (which is more accurate than ur speedo), dead reckoning blah blah…I love it! Cos it idiot proofs the trip and reduces stress of trying to find your way to destination. Am now that one step closer to the bat mobile which I was raving about the last time. :)
