Mateuszganko do you use this code on Mavlink version (for Arducopter) or MSP version ( for Multiwii)....Do you maybe use "Minim-osd extra" code project?
It should auto detect baud-rate on all GPS-modules with a UART-output, as long as the signal-strength is within the normal range. A normal 3.3 V device is acceptable as a 3.3V signal will trigger the logic "high" on Atmega328, but if the signal is a lot lower than that, chances are logic levels will not be detected.
