New tunes have arrived in Los Santos but you will need to do some legwork in order to unlock them all, along with a GTA Online property or two.
Unlocking new songs from Los Santos Tuners update in GTA Online is pretty easy, all you need to know are the locations of the four USBs and pick them up.
Red USB sticks are what you are looking for in every site. Given the colour, it's easy to spot them against their backgrounds. Without further ado, let's get into the locations.
You will need to enter the nightclub office and you will find the USB on the desk that has a computer that you can use to browse the internet, not the one you use to manage the nightclub. For additional clarity, here is a screenshot of what it looks like.
You can find another USB on the bar in the arcade so take the front entrance. Since the stick is red and the bar is white, it's easy to spot next to a few glasses of alcoholic beverages.
USB in Diamond can be found on the Rooftop Terrace. If you have a Penthouse, you can exit to the terrace and pop up next to the target location. Alternatively, just enter the casino regularly, and take the first left to reach the elevator. Go to the roof and then look for the nearby group of hot tubs below you. Jump down to their level.
There is a row of tables next to the hot tubs on the terrace and the table you are looking for is next to the hot tub closest to the elevator.
LS Car Meet mod shop
Once you're inside the LS Car Meet warehouse, just look for the mod shop and go to the mechanic. The USB will be on his tool table which is also red.
