The local shop sells clarion(along with Eclipse), and I am good friends with the owners so I am there alot. I have messed around with the 925(virtually the same as the 935), and I don't like it at all. The motorized face works ok, but the 2nd, drop down part is kind of clunky(and all the moving parts and clunky just don't mix with cold winters...I live in Maine). The shop sold ONE of the 925s as far as I know. It came back defective, so they swapped it out for the other 925 they had in stock. If I was buying a clarion(very reliable brand, but I have run eclipse for many years), I would go with the 835mp if I was buying new.
I too would like to know what all the bad things are about the 2003 clarions. The shop hasn't had any issues with them yet as far as I know.
