I contacted Satnaveasy initially to find GPS accessories, and boy do they have a wide choice.
My items were purchased and delivered within 2 days. It really did save my holiday. Not much point in having a sat nav if you can't mount the thing!
During the holiday I was having problems with my satnav (wish I had bought that from Satnaveasy). I called the office in the UK from Italy and a nice guy called Josh talked me through changing the settings on my sat nav so that it finally took me the right way. The next time I need anything sat nav, I know where I am going.
