USB Memory stick

[alfagt]

I have been having a few issues with USB memory sticks with my 67 plate Rav4.

I spoke to my local Toyota dealer service department who advised that the media centre can cope with USB sticks up to 64GB, however I am finding that if the stick contains more than about 1.4GB of data it will not read correctly.

Can anyone advise what the max size really is ?

USB drives must be formatted as FAT32. The Windows upper limit on size is 32GB (but that is not the FAT32 limit).

Map updates are of the order of 16GB so the actual data limit must be in excess of that.

But I suspect that you are really seeking an answer in relation to media files? In which case the limit is based on file structure, number of files and the Touch 2 systems ability to index the file structure.

Start by checking the media system manual for your car ... 😉

I have my media on a 4GB stick which worked perfectly happily on my Touch2 system.

You also need to format a new memory stick before you use it.

Some of them contain protection, which isn't needed.

I have used a number of sticks - all FAT32 formatted - the media centre will read them all but if there is more than about 1.4Gb of data the indexing gets corrupt, when I check them with my PC they are not corrupt and chkdsk gives no errors.

I have reviewed the Navigation and Multimedia system owner's manual but this gives no guidance regarding size or frankly any technical details.

How many files are in 1.4Gb of data?

[alfagt]

Not sure how many files but certainly less than 100

RTFM ... 😉

The information you are looking for is one pages 73 - 75 of your media system manual. Specifically:

Thank you - I had not found this page.

The problem remains that I am nowhere near these upper limits when the indexing gets corrupt.  So I wonder if the unit itself is being the problem.

I think it will be a file format issue or too high a bit rate

also the units only allow for a certain folder structure/depth for play lists
