stock bose systems crap!

first off my name is carl, im a newbie so no soaking my head in the toilet.  i searched for a post for my ? and never found so ill ask ya guys.  last night after driving home from wally world i noticed my stock bose navigation on my cts was acting kind of funny. the selectors to the right wont work.  to me i think the things are junk but knowing that that is pretty much the brains of my car would i be throwing away the value of my car if i bought an aftermarket dvd/nav player i know i wont have the "headlamps suggested" or the "service steering soon" <-dont ask, lol but would they be able to still reset the oil?  thanks for any replys i know we dont get paid to be here but any question is greatly appriciated ;)

??? What are you asking?

would they stil be able to reset the "change oil soon" when then oil oil is changed. 

Its very unlikely, unless A/M unit is designed for you car not universal.

thanks slowroll

i have bose in my allante. had radio and speakers rebuilt, very costly. it,s no better than delco.

Lets put it like this . I never met a Bose system that I didn''t like. I have had them in 6 different Acura''s and  my Allante,they were all good but the one in my STS IS OFF THE CHAIN to say the least, the only system that I heard that will compete is the Mark Levinson in the LS 460.
