I thought this deserved a mention. The Simrad 35 radio on my 2014 OC 45 was malfunctioning. My dealer did an update and the RS base unit worked great but the handheld HS not. I read that I needed to send it in to update. I notified Simrad and they sent me a return mailer. They did not update the radio. Instead they sent me a brand new handheld which works perfectly. Kudos to Simrad. There are still good companies out there.
