I would not recommend anyone to buy this product. Not only was the lead too short and therefore did not reach from the cigarette lighter socket to the windscreen where the Sat Nav is mounted but also the connection jack that goes into the Sat Nav was not a tight fitting. If the lead moved slightly it would not charge. I have since returned the product as it is unuasble unless you place the Sat Nav on the front passenger seat and who would do that. Tesco Direct sell one which is more money but worth it.
