Buick Verano 18 models can use 64gu disk. Valeant's U disk and SD card only support the playback of lossless wav music, and other lossless compressed ape and flac are not supported. It is best to buy a USB flash drive in 3.0 format of 64G or above, which is fast and avoids lags. U disk also supports playing 5.1-channel PCM format.
