navigation in dash

hi, im looking for a navigation in dash setup.

i don't want to spend too much (-600)
I would like :
a dvd player
touch screen
some sort of ipod hook up
car steering wheel controls
a user friendly navigation
navigation upgrades that are free(is this possible?) if not very cheap.

im "not" going to put an amp or sub so i dont need any extra power


thanks for all the help. sorry if this thread is already made. i just got sick of looking through every good, great , best , top navi, navigation,gps, in dash....... thread and finding that the best is pioneer, kenwood, alpine.....


any input would be appreciated.

 

thanks

 

Mr Brown can you navigate and watch DVD movie at same time with those models?
