I have a 2006 Adventure. My Navigator III and cradle have too many issues that I am tired of dealing with. Small memory, dealing with garmin sync software and multiple garmin accounts with lifetime subscriptions, cleaning connectors.. Has anyone installed the Navigator V with cradle on an older, non water cooled Adventure or GS? Will the installation package use the same power connector that the Nav III plugs in to? Is the sound plug in the Nav 5 cradle the same size as the nav 3 cradle? (I run a cable from the navigation cradle to my Autocom) What I am wondering is the installation of the Nav V as simple as removing all the Nav 3 stuff, and just plugging in the Nav 5 and installing the Nav 5 cradle?
