====== Sony MDX-5V101R ======

{{page>equipment:infobox_template}}

Sony developed the MDX-5V101R for Volkswagen Japan as an OEM radio for the MKIV Passat/Jetta/Golf released in 1998-1999. Shares a lot in common with the [[equipment:sony:auto:mdx-5v101p| MDX-5V101P]]

The unit turns on and off by depressing the volume knob. Buttons not found on US radios and their function:

Ti = Traffic information, a special frequency used in Japan\\ 
SCRL = Begins scrolling of disk name or track text if they are too long to fit.\\ 
AS = Auto Store. Holding AS down tells the unit to store radio stations it has scanned\\ 
DSPL = Switches between 3 modes for what info the faceplate should display.\\ 
  - Disk#; Disk Name; Total Tracks; Folder name(s) ▶ \\ 
  - Track Name
  - Track #, Time Elapsed\\ 
REP = Toggles replay\\ 
SHUF = Begins cycling a 2 digit random number generator for a couple seconds before picking a track. Rumor has it if 666 ever comes up you die instantly, your soul claimed by Deezelbub.

Despite using the same ISO and mini-ISO connectors as radios for the US and EU markets, the 5V101R changes the pin assignments. It also differs by using the Sony Uni-link protocol for communicating with dash and trunk mounted accessories, breaking compatibility. It has only one DATA pin for accessories where US and EU market radios have DATA IN and DATA OUT. The radio also has a GALA pin connection to raise and lower the volume with vehicle speed changes. 

Because theft does not exist in Japan, the MDX-5V101R has no radio code security feature, making them plug and play. Unlike US and EU market radios.

A service manual has not yet been found but the [[equipment:sony:auto:mdx-c5970|MDX-C5970]] shares a similar layout, the same ATRAC chipset as well as front faceplate controller chipset. The MDX-C5970 uses the MG-164N-138 md unit, which appears identical to the one used in the MDX-5V101R.
