indash DVD

I am about to purchase the Pioneer AVX-P7300DVD 7 inch indash screen that also has the built in DVD player. I just need to know of the brain part is completely neccessary. I believe the brain model number is Pioneer AVMP9000R AV. I am looknig to buy it within the next 24 to 48 hours so any help would be good. All the guy is selling is the monitor and dvd player, but he doesnt have the brain. let me know asap. thanks...

Will anybody help me?

And I know this is a noob question but what is this whole bump thing. I know its to keep the thread alive but when doyou know when to do it.

There's no set rules for bumping, just do it when you think it's appropriate. (like once or twice per 24 hours, don't do it every 5 mins)

What I understand is that the brain is necessary. To be honest I don't know how much tho. I'm pretty sure it controls the DVD/CD etc. functions. If you don't have it it's pretty much just like having a monitor, BUT once again I'm not sure how much it'll work w/o it. You might be able to hook up a PS2 or XBOX to it and use that to play dvds or use the monitor w/ another HU and play cds.......... Personally I'd reccomend just buying the brain and keep everything as it's suppost to be. The brain's not just an accessory and IS necessary to get everything out of the indash DVD b/c the indash just can't hold all the electronics necessary, not enough space.

Bottom line, without the brain you can't do jack ****. You'll just have a screen that's looks nice. Thats why when you buy brand new the brain is included.
