I don't mean to hijack this thread at all. But iGO8 should have been included in the poll. IMHO, iGO8 was the best nav ever produced. Not only was its directions spot-on but it also had many more settings/options than the navs that followed. As for the TTS, I can make it do tricks and say anything I want it to. Plus I can change its pronunciation to anything. I only wish that it was available for Android and not just WinCE. Igo8 is much better than any Primo. Heck, Amigo was better than Primo.
