the product be quite good and reliable . I be new in US and this product have be the only source by which I be survive - visit to various client across the state due to the travel nature of my job . except for some area like make a u - turn or in highway where you need to take a right turn and then round about to take a left , the product fail to highlight that . it only say you to take a left turn whereas left turn in reality be not permissible .
