Review on Humminbird GRP Precision GPS Receiver by Bud Crabtree

Dad had to upgrade his receiver as the old one wore out. This one is faster than his older one and still worked with his communication system after being wired differently. Installation was easy and there were more than enough cables to plug it where you need it. Make sure it works with the system and search engines you are currently using. Humminbird updates its plugs with new items, so it's best to double-check before you spend any money.
