I am considering getting the standard JBL system with no NAV. It appears to be the exact same just not NAV ability. Does anyone know if that is true? Also, if you do NOT get the NAV, can you added in a NAV later (reader dash mounted or replace the JBL with a NAV stereo)?

Also, the options packages that are "available" in each area seem to have changed. The leather package includes the JBL NAV and a preferred package. Did anyone purchase their TCH and "pick and choose" options vs going with a package?

Thanks,
Mike
