I'm just wondering if anyone has had any success using a Navigon sat-nav (especially the 2150max) and getting it to pair so you can make/receive calls on the iPhone. Their support says it is just 'incompatible' and all pairing attempts I make fail - Maybe they just don't work together... any chance someone has found a way to do it? Any guesses as to whether this is a problem with the software on the sat-nav or the iPhone? We all know how useless the iPhones bluetooth is (no file sharing etc.) but I know that some hands-free kits like this do work.
