handsfree disconnects

Hello! I have upgraded to a new Iphone 11. Since then I have not been able to connect via cable to my R LINK 2. Every single time I connect via cable to R LINK handsfree disconnects from R LINK 2. Phone charges only. I am not able to select phone book in the R LINK or to do anything else with my phone via R LINK 2. I have tried to reboot my phone first. Then I have reset whole R LINK 2 to factory settings and Iphone again. I have tried my wifes Iphone X and there was no issue what so ever. I am using only original cable to connect with the R LINK 2. Would you have any idea?
