has anyone tried to do many/most/ALL!? of these audio upgrades?

i need some help. i will spare no expense!


i have a 2005 prius. the 2006, 2007, and 2008 prius has a much better stereo system in the dash, with more features available too. what do i have to do to get my stereo replaced with one of those? you can find more details below. please advise, thanks in advance. dan



this i what i have:
2005 Toyota Prius Sedan
with Navigation system
Factory Stereo Installed
plus Bazooka subwoofer (circuit city installed)

the factory installed stereo is a JBL 6 disc in-dash cd player with cassette and large touch screen gps.
it has steering wheel and voice controls of the volume, tracks, etc that i would like to keep using.
it also has cd-text display, which i love.


this is the problem:
sound quality is important to me.
there is no mp3 or wma playback.
there is no dvda or sacd playback.
there is no aux, ipod, hd or satelite radio direct input.
i have to fm transmit everything, which sucks.
crappy internal satelite radio antenna (loses signal under bridges, etc).
when i want to update my gps maps each year, the new disc costs $250 (like the price of an entire gps receiver!)


this is what i would love to have:
cd playback
sacd playback
dvda playback
mp3 playback
wma playback
hd radio playback
built-in sirius satelite radio
direct ipod input
everything above displaying info on the screen
cd-text reading
sirius/xm/hd antenna professionally roof mounted
good gps system with regular inexpensive map updates
back-up camera
touch screen, steering wheel, and voice controls over most of everything.


this is what i dont care if i have or not:
i have no need for AM, FM, or cassette playback.
i dont care if there is a remote control or anything.
i subscribe to sirius radio, but could also use xm ready for when they merge.
i dont plan on watching anything on the screen, so i dont really need dvd movie playback etc.
BUT, if i could get a back-up camera and show it on the screen, i would definitely want that.
it would be nice if there is an internal hard drive and or memory stick / card reader for stuff.
i would love to have real time traffic, but the absence of this feature is not a deal killer for me.
i really only need one disc in-dash at a time; more is nice, but not a make or break thing.
i dont really want a multi cd jukebox in the trunk or anything, i prefer dash access.


however:
ok so i seriously doubt there is a unit out there that can do all of the above. but i really hope you can figure out some options to help me accomplish as many of these requirements as possible. its ok with me if its one major unit with some add-ons if necessary. i know i have seen many different pieces of hardware out there that can do these things. if there really isnt one out or coming that can do everything, what can do the most and fits our priuses? also i have no ability to install any of this stuff myself, so i would be bringing my car to experts for professional setup and wiring etc.

thanks for reading. please take your time in researching and responding to this, i am deferring to your expert knowledge here. if there is nothing out right now that would be applicable, but you are aware of devices coming in the near future, thats ok too. just let me know the timeframes and pricing so we can make a determination together. if you have any questions or would like any clarification on what i have written here, please feel free to email me at [email protected] at anytime. thanks again
