Kenwood - Garmin KNA G610 Map Update Problems
on March 30, 2012
After purchasing a Kenwood DDX616 unit, and associated Kenwood KNA-G610 navigation module, powered by Garmin, for the ability to update future maps via the SD card slot, I've learned that the Garmin Kenwood support team is unable to resolve a problem of continuous rebooting of the system. After two weeks of troubleshooting with their "experts," they've told me "We've put a request in to our Engineer's and it may take up to a few months to even get a response back from them." It's very disappointing to learn that my navigation maps may never be updated, despite that being the reason for my purchase of the unit. Garmin and Kenwood need to get their acts together if they plan to offer products to the public that are not falsely advertised. Very disappointing.
