The Altitude seemed off on my Legend by about 30 feet. I have easy access to sea level and wanted to set it to zero. In order to do this, I must turn off my GPS first. How does this help? When I set it to zero and turned it back on I was 80 ft below water! Is there something I'm missing in the instructions, or is it something you just don't try to fix?
I want to die like my grandfather did, peacefully in his sleep. Not screaming and yelling like the passengers in his car.
