Is anyone set up to use their tablet (ipad, Galaxy tab, or similar) as a GPS? I have been using a Garmin 62s for a while now. It works awesome but I find myself using my cell phone more and more. With the Navionics app I can scout, plan, and create routes all within a single unit. With the Garmin I have to scout on google earth and then move all my points into homeport before creating a route in homeport. Navionics also allows me to overlay Google earth on the navigation software. The garmin does something similar but the screen sucks and it's impossible to use unless you're on foot. Thoughts? I can set up a nice rig with a Galaxy tab 4 7 for less than $300 and be able to everything from one unit. My biggest worry is heat and salt/water intrusion.
