I just bought a 2012 G37S with the navi. Overall, I absolutely LOVE the car, but I am having an issue with the USB audio using a USB flash drive.

I have just under 30 GB of music (all MP3s encoded at 256k), so I bought a 64 GB USB flash drive that I have copied my MP3s to. I have been through the discussions of how to order them properly (I used Media Monkey and everything copied over in the right order), and songs are in the right order on the drive. I have approximately 3300 songs organized in 455 folders with no more than 3 levels of folders. According to p. 4-48 of the owner's manual, I should be able to have 5000 songs in up to 512 folders with up to 8 levels of depth, but the folder listing on the screen in the car shows only 255 folders. What am I missing?

I did note that p. 4-48 lists specs for "Type A" of the head unit, which based on p. 4-55 is the type I have (Type B is shown on p. 4-56). The specs for the Type B head unit does say that it can see a max of 255 folders, but based on the pictures I don't have a Type B unit. Am I missing something? Is 64 GB too big for the system to read?

 

Man think of all the scrolling you're gonna have to do! Do you need all 30 GB's accessible on the road?

 

I have 60gb.

 

It is true that you would have to do a lot of scrolling with that many folders...but I am typically a set it and let it roll kind of listener. One option would be to just build playlists on the USB stick.

I am currently going to split my collection across two sticks and see how it goes...but I would still like an answer to why it is not working as stated in the owner's manual. Hopefully someone here will have an answer or my dealer can dig it out.

Thanks...

 

dbobke - I have a 64GB flash drive I am using in my 2010 xS sedan and notice that even with the drive ~ 1/4 full, there is often significant lag time after starting the vehicle that the display shows "Reading USB drive". Sometimes I can drive for 10-15 minutes and it will never load.

Do you have any similar issues? If you ever did, how did you improve it?

 

FYI even though you don't have that flash drive full it is a large flash drive. If I recall right from the owners manual you are not supposed to use one that large. It might be a good idea to read through your owners manual to see what size works correctly. Yes you can have to much memory in the case of the head unit trying to read what is on the drive. Oh and this can all go away by using an ipod........................

 

I could be wrong about this as maybe it was the older models that had the problem of not being able to read anything over 2 gig, after reading some threads people definately have been using bigger flash drives. I would still read up on it as you have a whole book on the system. Also once again I will say an ipod is the best way to go.
