Navcore 9501 RIDER V5 and Navcore 9501 CAR & RIDER by MaSp.

I have connected Cardo and Chinese intercoms to a TomTom Rider k2 and they all worked well, try installing this navcore 9501 Rider V5 that I have published to see if it works for you, first reset the previous intercom connections that you want to link.
Try and tell us please.

Note: On some occasion you have connected the intercom with the gps for the fifth or sixth time that it has been tested, if it says impossible to connect, repeat more times and remember that the intercom is in paring mode.
