Bluespark

Allows me to change maps at the touch of a button. Magic.

Once the box was relocated to a more suitable location in the engine bay, the app worked great. I can easily control the settings from inside my car. Great app, thank you!!

Allows adjustment of the maps while driving and even remote software updates. This is awesome but you have to have a Bluetooth enabled Bluespark box to use it. I have one new one and one older non-Bluetooth unit, which I hope can be upgraded.
