What JVC Double Din do get?

[Mark2.2]

I am stuck on two JVC units to buy for my Vectra. The first one is a Jvc KW-AVX840 and the other one is a JVC KW-NT30. The first one is cheaper as it's not a dedicated sat nav unit. The second one costs about £200 more, but comes with built in sat nav and built in SD card different to the other one. I am going for the JVC as the full face is removable to stop theft of the units. What one should I go for? Thanks

I am going to go for the second one, it makes sense I think lol

I am looking into getting a rear number plate rear view camera. The rear view camera I am looking at says "TV System: NTSC default & PAL request" . Is this ok for my new JVC system as I don't understand the above default or PAL parts. Cheers for any info
