My Ultima XL that I had removed from my RS is now installed on the GT. It seems it was not an easy job, and that the technician spent a long time puzzling, but they managed to make a very very clean job. Nothing visible at first glimpse.
Everything is ready to receive the 2820 when it gets delivered. All the wiring for it is already on, as well as the GTM 11 RDS receiver. All neatly installed. The only visible parts are the two helmet connectors and the cable that connects the mobile phone, when no phone is on.
By the way, I am looking for a 2.50 mm cinch plug adaptor block for a Nokia 6680 if anyone could help me, can you please PM me ?
