Hi Guys - I am new to this forum & would appreciate your help.

I recently bought a chinese car DVD unit. Came with old iGo 8.0 maps so replaced them with 8.3 (Sensis Q4 2012 maps from this site). Everything works fine except:

1. The street names are not pronounced by the lady (it just says turn right/left etc.,). & also it doesn't have Australian speaking lady (only UK).How do I get these two features?
2. I have also downloaded latest primo maps on separate SDcard. All works fine again but it loses signal every few seconds. No signal is lost if I just use iGo maps without primo version.

Any help would be great !

Thanks

Shal
