I'd love to be able to add an instrument guage set to my 04 7 series. Does anyone know if there is a package that would provide display on the NAV screen. This would be great to have and so far I haven't found it within BMW......is there an aftermarket that could integrate like I just did with my bluetooth cell phone?? I hate depending on the "it's broken" or "check engine" lights....I'd like to check everything in an ongoing basis. Thanks for your help........Pete G
