igo8 is probably the best map prog w/ TTS. I group Igo8(and others like iguidance, TomTom) separate from gmap& Bing since they don't require data connection to work (good for 0versea). Igo8 might be a little harder to get working but it is the most customizable and also have very extensive map collections. There is a thread on getting TTS to work on here in sticky. I put the link for the smaller speech pack which definitely work and requires less memory as well as working multi resolution data and branding.zip.
