For help with resetting an MMSI number, you can reach out to one of our authorized international dealers for help locally. You will find a list of them HERE.
We also offer a reset service here at Cobra. This service costs $39.95 (includes return shipping) and is performed at our Tennessee facility. This typically takes 2-3 weeks to complete. Please contact us via 800-543-1608 or open a support ticket at https://www.cobra.com/pages/contact-us to set up this service.
