Anyone have a 350z that had an OEM navigation in it and they replaced it with an aftermarket unit (either in HU or Garmin/Tom Tom type). Wanted to get an idea of what they replaced, removed, modified, etc.

Would I need to get a new center console w/ cubby (since there would be a huge hole if you remove the navigation screen)? Or could I get an aftermarket system to mount in the place where the OEM navi screen was to begin with?

I have a 2008 roadster.

Any opinions/help would be much appreciated.
