Finally got my mp3 working, But having trouble getting the pie to connect top the software. I don't get any beeps or for that matter any noise when connected. Not obvious but I have tried connecing with the pie turned on at the battery and of, but still no connect. noticed the reverse needs to be unselected. but stil no go . I need to turn down the pedal assist as it is to violent. also need to enable regen brake . any ideas appreciated
