Which model is compatible with a 2005 EC300? I've read conflicting reports.
One says the 202-101 is the one to use, and another says 202-111. Don't want to got through the hassle of sending back a wrong one if I can help it.
Thanks
What is the difference? Will one work with a battery whole the other doesn't?
I have on 9n my 2011 ec250 and even when the internal battery died, when I would key-on, it would fire up and work as it should.
Maybe this will help.
