Raymarine tiller pilot st 1000 connected to Garmin gps 521s / 520

[bigboy]

Good Morning my friends, any one of you has a raymarine tiller pilot connected to the gps ? I have had mine for 5 years but never managed to connect it to my gps. Maybe someone who has it on his can come and show me as i really would not like to bring the raymarine guy as he is completely crap ! Been having issues with the TP for 3 years and finally we had to send it out to raymarine for them to establish the problem as he was checking it each time telling me that all is working as it should.

any help would be greatly appreciated as i always wanted to have it connectedto the gps.

thanks

Kane
