changing battery

[simona]

Battery wouldnt start the car last night but everything else have juice. Jump started it with a portable jumperstarter.

I have CPO warranty, is the battery replacement covered?

If not, it looks pretty easy for a DYI but do I need radio code for my RNS-E?

I have taken out my radio a couple times and it has not needed a security code. I am not sure if the Nav is any different.
