if you posted a pic of the hole or posted the dimensions, it would help us help you.
their are usually two types of RV entertainment systems, A and B.
the A is tall and narrower while the B is wider and shorter.
Concertone makes units in both sizes. Jensen only makes the B.
the B is more common and easier to find replacements. as far as i know, i've only seen the A in the Concertone brand.
