Harry's GPS Suite Forum

I'm struggling to get LapTimer GrandPrix to work with the following setup in my E46M:

• Android Xtron PB7646BAP Head Unit
• Xtron Bluetooth OBD2
• GoPro Hero 4 Black Edition

I was able to get all devices/sensors connected (including OBD2 not pictured and GoPro WiFi):


First issue I'm having is I cant get past the Calibration screen, it gets hung up on the second "Pitch Calibration":


Assuming I can get past that step I'm also not 100% clear on the video setup (I read the video doc). Can the GoPro be used as the primary camera? I could connect it to the head unit with USB or HDMI-to-RCA. Or, can it only be synched with a video directly from the head unit?

Hi,

There is no need to calibrate the accelerometer in your case. Please select "Internal Cam Preset" instead.
The GoPro needs to be connected using WiFi. Please see Video Documentation available from www.gps-laptimer.de/documentation
