this be my first experience with a GPS unit - neither my , nor my husband 's , car have gp install , and we never really care . but I be excite to get this gp unit and see what the fuss be all about ! I install the software on my computer , update the unit , charge it up and enter in some address . we go on vacation the other day and we use this unit to get to we resort 500 mile away from home . it give clear and concise direction , the voice on the unit be not annoying , and we actually decide to take a different exit , and the unit recalculate we route . for the price , it seem like a great gp . I really enjoy have it for we trip and look forward to use it again on another upcome trip . the suction to we front window work perfectly - no slip , fall , and no residue . 5 star for this gp !
