Rider Navcore on Go740?

I feel this must have been asked before but unusually I really can't find the answer.

I have a GO740 and have successfully updated it several times but now I'd like to try some of the functions of the Rider Navcore, so I'd really like to know if anyone can say for sure which Rider Navcore works the the GO 740 model. If nobody can say for certain, maybe someone with more knowledge than me could suggest which one may be the best one to experiment with?

I am guessing that the 'normal' maps work with the rider Navcore in the usual way?

Thanks for any input.
