I am not sure how many times I have to point this out....when the radio is changed the digital read out on the dash still works....mph avg...range....trip...it all works...the only thing that you have to do is account for the time change...so when it comes time to fall back or spring a head you pop out the heating/ac face plate...plug in the radio...adjust the time...unplug and reinstall the heating/ac plate...that is it..you lose nothing over OEM.
