There are two bank holiday weekends in April, with the royal wedding throwing in some much needed time off for the hard-working Brit. Having a street party? Thought not. If you are planning on using the time to get away from both the wedding and your hometown, you might want some help with the journey. Which is what CoPilot Live Europe is offering.Petrol prices for a UK trip might be sky high, but the CoPilot GPS software for your mobile phone should soften the blow, offered for Android and Windows Mobile phone users at 20% off from now until the end of April. Grab it here to get the deal and don't worry about the data charges as you go - unlike some of the free mobile navigation apps that download maps over the mobile internet on each trip, CoPilot Live stores its street maps onboard, so there’s no risk of getting stung by an enormous mobile bill when you get home.Other features include voice guidance and 3D maps, plus turn-by-turn directions, useful real-time information and advanced navigation features such as Lane Assist, Clear Turn and Driver Safety. If all of that appeals, you've got until 30th April to secure the discounted deal.
