Help with the new radio installation

I want to exchange the KD AVX 1 for the new multimedia CD/DVD radio from JVC. I find the radio simply hammer and doesn’t look so childish.. well back to the topic. Coming straight from Saturn what I noticed is that it is flat but already a corner stands out… measured 2.4 cm. But it’s very important to me that the flap still closes, but I doubt that with the measure. Can someone tell me if that fits? Would measure with me, the Prob is just the one that is just at the And I don’t want to pick him up until the evening, but I want to have the radio at home. So that I can continue with the system and the cables.So I ask for a quick answer- THANX –
