The cars without navagation will their be a door with storage area like the mazda 6. The preproduction car dash is solid 1 piece but the mazda rep said that might be because it was easier since it wasa pre-production and hand made.

 

This is the first I hear of this It would be nice because lator I can swap the bin for the Navi

 

This has been covered in another thread a long time ago... The cars without navigation will have a solid dash. No storage bin like the 350z. There are even pics of it somewhere...
