Brilliant! Brilliant! Brilliant! What service!! My GPS went wrong. After a phone call you got me a replacement and took my faulty unit back via courier. All within 24 hours. I just couldn't ask for better service. Please thank the lady I spoke to on the phone, she couldn't have been more helpful. This takes all the worries away from mail order.
