Yes, you can upgrade the firmware on your 18M by using COBRA's reprogramming software. We provide the firmware updates and the reprogramming software free of charge; however, you do need to purchase a Wireless Reprogrammer. For more information or to purchase, please visit our Wireless Reprogrammer product page.
For instructions on how to perform a firmware update please see How do I update the firmware on my equipment?
There is also the option to send your equipment to COBRA for an upgrade. COBRA does charge a small service fee of $5 per device + shipping for upgrades. The $5 fee includes a firmware upgrade and a COBRA 360 health check on your device. To request a return authorization number to send your equipment in for upgrade please email firstname.lastname@example.org.
