I have a gps + glonass I can program outgoing data, I believe that realdash reads the RMC sequence to work; in my case the data log is of the type $ GNRMC, 083825.200, A, 4554.732484, N, 01052.388933, E, 1.04,247.59,220121 , A * 7E and therefore does not work (rate 10Hz and Baudrate 115200)
in Realdash it is connected (COM3) to USB GPS USB 115200
