Hey I Need some help I have been looking for a new audio system for my mercedes but on crutchfield it claims that it will fit but on another website that sells the exact same model says it won't fit so I don't know which website to believe

http://www.crutchfield.com/p_110VM92...-VM9216BT.html <----- says it will fit

http://www.sonicelectronix.com/item_...%5BIgnore%5D=1 <----- says it won't

Would someone know which website would be wrong thanks.
