Default Clock battery?

Hello all. Does my 1998 coupe have an on-board battery within the original Bose head unit? Seems like lately when I do actually fire it up to go for a ride, I have to reset the clock to proper time. Maybe a CR2032 or other type of small battery? Thanks in advance.

Hard to diagnose from here, but perhaps during a cold start, or even a hot start, the battery is being loaded enough that it doesn't have enough voltage to keep the radio settings intact. How old is the battery? Have you had it load tested? Hope this helps...

As soon as the battery gets low, the OEM Radio and HUD will reset to default settings and the clock will show 12:00
