Dear Paul,
in our E-shop currently I''m afraid we do not offer mounts specifically for your model , but as a workaround I can suggest to search for mounts for MiVue 638/658 instead as these are quite similar. You will only need to detach the extra cover part that goes with the mount ( specific for the models MiVue 638/658) and leave only the main suction base with the ball-like end. You can afterwards use it for your MiVue 618
Thank you for taking the time to contact us.
Kind regards,
Ivaylo
