Help..losing electronics 1 by one.....

The other very cold morning here in Ma.(2 degrees),my heated steering wheel came on/off. Came on later. Next morning a conserve battery warning came on and no heated wheel. Later that day, stereo went off and came back on later. Now..no heated wheel or stereo at all. Stopped at local auto parts place free check on batt. showed batt 12.34(which I know from boating is low)and an alternator check and said they were both OK. Any ideas? 2003 E320 w/143k on it. Not sure if orig batt as I bought used 4 yrs ago.

I'm new to owning a MB (literally since 1/29/11) but from what I have read around the internet, have you checked the aux battery (if so equipped)? It seems that various electrical issues come up when the aux battery is low and needing to be charged or replaced.
