Also give a good look at a Hammerhead Karoo 2. Its a very polished and usable device. Arguably does navigation and TBT better than Garmin, certainly has nicer screens and maps. Doesn't have the battery life but thats sometimes only an issue if doing double centuries or touring someplace where you cannot charge and yiu can always run it on a battery stick. They are regularly updating, much better at bug fixes and updates than Garmin. The screen is only marginally smaller than a 1030.
