Hi Everyone

I have recently bought a Mini Roadster R59 Cooper S which has the retrofit navigation installation kit and a garmin nuvi sat nav. I noticed the sat nav was very loose so I removed the sat nav and there is a plastic ring with 3 lugs that holds the sat nav mount in place which has broken. The plastic rings are no longer produced but I am hoping to find one from either a company holding new/old stock, from a breakers yard or from an individual that has had the installation kit but removed it. Every website I have visited just informs me that the part is no longer available so I have joined this forum hoping for some help. In the picture below, the part I am after is number 3. Thanks in anticipation.... Andy C
