I am looking for a replacement car stereo for my wife. I would like to find a unit with the following qualities:

1.) Accepts a USB flash drive in the face of the unit. (a 64GB Mushkin Atom will only stick out 1/4"), as well as play WAV and MP3 CD's.

2.) Knob and buttons that will allow navigation up and down through tiers of a Windows tree file structure, and laterally through folders or files at a given tier.

3.) A display of sufficient length to identify the folders and files displayed.

I went to BestBuy with that 64GB flash drive loaded with 36GB of music and audiobooks. The contents were well within the maximum folder, maximum files per folder, maximum total files, and maximum number of tiers in the tree structure. It was structured as follows:
Music/Album Collection/Album/Song Tracks
Audiobooks/Type(Fiction or Non-Fiction)/Title/Tracks

The sales person could not show me a Kenwood or Pioneer unit that could be easily navigated. I had also used Kenwood Music Editor Light to create a database for the Kenwood units. Basically, all that could be done was to scroll through the entire database at the track level.

I can't believe that there is not a care stereo CD receiver out there that can do what I am looking for. I was led to understand that the only way to do it is by using a separate smart phone or MP3 player connected to the unit by USB or Bluetooth. I have already tried a Satechi Soundfly with the old stereo, and it was too quirky and inconsistent to be worthwhile.

I would appreciate it if anyone can recommend a standalone car stereo that can do what I am looking for. My basic goal is "simplicity for the sake of safety"
