OKAY, my Car Navigation has disappeared.
Um.... this is kinda scaring me.
Thats becasue you didn't read through the menu (or this thread) when you installed the ROM. The final step of installation gives you the option to install a few cunstom options (2.1 browser etc.) and then the next menu asks which ones you want to remove.
You never unchecked it. Reload the root app and pay attention. There is a further in depth explination by Camel earlier on in this thread
