The smart car I got from my uncle has a few little issues, one being that there is an issue with the Bluetooth button. You'll be driving along and I hear a beep and the sound on the radio shuts off for a few seconds and comes back. If you tap the button it usually works again as well. I was told the button sticks. Is there a way to replace the button or does anyone have an idea on how to fix this? I haven't messed with the Bluetooth yet but would like to! That would be a beneficial feature for me.
