I have a Gateway 300 (GW33TO1 or GW33LS1) for Lexus. It plays the music for 1 minute after goes to the next track automatically. Is there any way to fix this problem?

The mentioned problem could appears only in rare cases. If you experience the same issue as above, please follow the recommended steps below and update the firmware of the Gateway 300. 

Follow the steps below to update firmware:
Extract the G3AE_UPD.ROM file from the update package and copy to the root of a USB  
flash drive, then connect the USB drive to the Gateway while it is powered up.
If  there  is  an  iPod  connected  to  Gateway  you  can  leave  as  it  is,  in  any  playback  mode  or
status, you do not need to disconnect or stop playback.
 
Update  procedure  will  start  automatically  within  a  few  seconds  and  takes  approximately
1 minute. Do not disconnect the USB drive within this time. During the update the head unit
(car stereo) turns to tuner mode and the Gateway restarts.   
 
When finished, you may need to select the Gateway as a source to reach the Gateway functionalities again.  
 
After  a  successful  update  G3AE_UPD.ROM  is  deleted  from  the  USB  flash  drive  and
GW_EES.BIN file will appear with the new software version. 

The firmware can be downloaded from here
