Summary: It seems that you can't upgrade your mobile phone as the TomTom won't pair with any modern phone tried every one in the phone shop only works with old phones. Getting hold of Tom Tom is difficult.
Excerpt: Over all good item could do with a jack plug for external speakers or for motorcycle intercom, thought we would have to buy a up to date headset to use with it, but a friend has one and he said try it without buying, and its fine so happy when we come into a bit more money we might buy in the future...
Summary: Very good. So far works really well. A goodish price for a waterproof motorcycle satnav. As others say its a shame it doesn't come with proper powered mount which I could only find on here for £54. Battery power is very good but not as stated. You will definitely get a solid 4 1/2 hours use.
Summary: Had my first Rider stolen, replaced it with another. I thought it was good before, new model even better wth full postcode search and enhanced screen grahics. I have used it throughout Europe, campsite function usefull in citys when looking for place to set after a longdays ride.
Summary: Yes this Satnav will get you to your destination, but am I the only person to find the IQ routes system a royal pain. It seems that there are only two options for road choices, Motorways or back roads.
Summary: This is a very nice piece of kit! The day/ night screens are a great idea and the screen directions are clear enough that when your Bluetooth headset dies (like mine did - not supplied with this product) you can easily manage without!
