We use a laptop with Delorme Street Atlas loaded on it. We put the computer on the console with no slip rubber mat under it. We keep the generator on for A/C's when traveling so power is no problem. LOVE the 15" display! It lets you set your speed on different road types. With a little bit of practice ETA is almost always right on the money. Haven't found a ht & width feature yet but it does allow for road types to avoid when using the routing feature. GPS antenna is USB.
