2006 e66 with NAVI03. I like the original amber-colored circle for the car position and amber-colored zoom. When I inserted 2010.2 DVD it upgraded to a gray-colored cirle and once you change the zoom on the map the zoom changes its' color to gray. I tried to reload v27 software but it didn't help. I think the navigation software settings only upgrade to the next version of the software (v27 is original for my unit, i.e. v9.3.0C), but not downgrade. When I inserted the original 2006.2 DVD the colors for items mentioned didn't change back but stayed. I tried to play with the software CDs (v27, v32, loaded a v26 which is prior to v27) but nothing helped.
