Where do these belong?

The guy I bought this car from had one of these inside of the glove box and the other was zip tied to the trim above the pedals. The ziptie broke and it was in the way of my pedals so I had to unplug it. A quick search showed me the one with the bigger label was the nav system and the other was the radio. Does anyone know where these belong? Having it ziptied and in the glove box isnt going to work for me.

They are both navigation, you can find the location on realoem.com , I believe the navigation drive belongs in the trunk.

Ditto above. The 1st pic (ending in 226) is a Nav CPU...the 2nd pic is the "radio" (ending in 213) that is used when you have onBoard navigation option.

Ditto again, the Nav CPU is usually mounted in the left side of the trunk...and so is the "radio" BMW53 (in this case) in the sedans. In the Tourings...the radio is located below the cargo floor.

Since the 11 digit BMW part nbrs a clearly visible...you can input either of those numbers into the part nbr search on any online parts database to find more info about them. And to find which other BMW models may have used the same part:


The MK1, MK2, MK3, MK 4 Nav CPU were all located in the same place (but have different part nbrs:
