Welcome, nice purchase and good colour. I have a 2012 sports yellow trophee without satnav. I don't think the satnav is compatible with RS monitor until RS monitor 2.0 which is available from 265 Redbull RB8 onwards. Hope this help.
Welcome to the forum MW 787, I was in a similar situation changed from a Porsche 944 turbo after 15 years of ownership to a sports yellow RS 250 trophee last December; very happy with the purchase. I am in Boxhill area hope to you on the road sometime soon.
