07 Showstopper

I'm done with my problem causing shaker500, so I'm looking to go aftermarket on the headunit. I did a bunch of reseach last night and heres my short list as of right now:
Pioneer FH-P8000bt
Pioneer Avic-f90bt
Pioneer Avic-f700bt
Pioneer Avic-f900bt

Im really leaning towards one of the first two, so if any of you guys could weigh in thatd be sick.

Have you consider the Avic Z110bt unit? I had it installed on my '06 and it was a great little HU and had a pretty good OEM look.

It looks nice! But heres actually kind of the things I'm looking for: low load time(or none at all, great sound quality, and a **** for the volume(just a personal preference). It didnt look like that one had a volume **** if I'm looking at the right one?

Oh and ipod capibility

KXRM

Yea it has all that but no ****.

Hows the glare on the screen with the windows down? Thats one reson I really liked the pioneer fh-p8000bt because it elimates that factor. I love rollin around town with the windows down

I had no issue with glare and you can also tie the HU into the lights so that it has different settings based on night or daytime use.

Okay good to know in case i do go touchscreen. I really would like one thats mostly buttons though if thats possible. Like buttons for on/off, volume, track skip, fm tuning, etc. Hopefully someone can point me in the right direction on this. And I really stress having a LOW load time or none at all would be great!

KXRM

Well there is a string of buttons along the bottom of the HU. I found most functions available there. The audio load time on the z110bt was about 5-10 seconds, well before the interface fully loaded.

So if you turn it off then back on while driving does it have to reboot all over again? And how do you change the volume on it? Oh and hows it with ipod connectivity? Any lag with that? And is the touch screen nice and easy to mange or does it make you want to punch it? Im not patient with technology that doesnt work lol. Sorry for all the questions
