my husband be not like I and will not stop to ask direction , especially when we need to traverse congested or suburban , or even rural area . we have a 5th wheel travel trailer and enjoy go about the country periodically . I buy this specifically for he to use when we travel in two vehicle in the event we become separate in traffic . we do travel with walkie-talkie but I want a good system for he in case of problem . I particularly like the instruction , `` such as do not take the next turn but take the road immediately follow , '' the advance notice of road or direction change , and they be simple enough for anyone to follow ... and it be hand free , unlike use the walkie-talkie . I want a gp with lifetime update so I pick this gp over a less expensive unit . due to we aging eye , I also choose the larger screen , and actually like the 5 '' screen although I would have love the 7 '' screen . I have no problem see the GPS screen , even located 2-3 foot from the driver 's seat . I would not want one less than the 5 '' screen . I hope you enjoy the GPS you select and I strongly recommend this model .
