Just recently purchased Navigon 2410 in UK. Would like to load USA map, but the Q4/2009 from NAvigon site is too expensive. Saw one available in ebay but Q1/2010 version. Seller confirms it is useable but just want to double check. The map listed in navigon uk site for the 2410 is a Q4/2009. Will the Q1/2010 version work.
