I have never used a GPS outside of my phone, but suddenly I want to give TomTom a shot. Qcom on Youtube has modded his personal device with various pony voices, and in this little demo video he shows off Fluttershy. Nothing is more relaxing than being guided by the best pony on the second weekend of each month (And Wednesdays, but don't tell Cereal. He thinks that is Rarity day lol).
Anyway, check it out after the break!
