I don't know what else to do.
Perhaps the Naza FC is bad.
If your original Naza connects fine then your computer is OK. No need to mess with it.
It seems a new VU unit didn't help so that leaves the Naza. To check it simply replace the old Naza on your 450 with the new one and see if you get anywhere. You just need to make the connections temporarily. You don't have to really mount it. Should only take a few minutes to check.
