Just got the combo unit

[Naterj14]

We'll my Dad and I went and picked up our Lowrance lms 527 i today can't wait to get it in. One question thought I think it was Mac Attack that had a unit similar to this one, when i turn the unit so the screen is facing the celling you can see a little line at the top right hand corner and maybe an 1/8 from the top and running an inch to the left, and when you look it how it would be mounted you can't see it, does your have that? Also has anyone hooked the dsc radios up to their gps's?
