The Navigation app keeps on talking rubbish to me. It just bursts into speech starting off with "XML VERSION"....and talks a load of XML code to me. There is no Navigation app in Manage Applications for me to try to do a clear cache/data etc. so I dont have a clue what to try! I'm now on Sicopat's KI4 ROM, but this happened to me when I was on stock KG3 also so its nothing to do with me upgrading.
