I am in process of changing my audio and bought the Techno Research Alaris tool to do my own flashes. But since I had Stage II Boom I first had to have the dealer remove that flash since the TR tool advises against flashing over a stage II flash.
When I took to dealer I asked them to flash it to either stock or 8/2. Tech came and got me and brought me back to bike and showed me on the screen that he didnt have those options enabled because it saw 1 amp. So I had to go with a 2 speaker/1 amp flash. Tech said at some point recently they updated all the Harley Tech tools, and it has removed his ability to flash stuff or make changes to things that are not installed or installed.

OP, there looks ot be several authorized RF dealers near you. They should also be able to do the flash.

Good luck. Just remember that with the BT355 you don't want a flash that flattens the EQ (a stock HD flash will not). If you are forced to use an RF flash that does flatten the EQ you will want to replace the BT355 with a simple LoC like the PAC SNI-15

Can you flash 6.5 Boom through the USB in dash?
I have a 2016 Road Glide. It has the 22.1.2 flash. Having issues with the navigation. Is it possible to flash the head unit to the 22.1.3 version on my own through the USB in the compartment to the right in the fairing?

You are looking at updating the HU software which is different than flashing. Flashing must be done using a flashing device through the OBD-II connector and the CAN bus. The software is updated using the USB port and a properly formatted USB drive.
software and instructions are found here
There are also a million threads and YouTube videos on how to do it.

Maybe why I couldn't find anything online about it was because I was using the term "flash". My question tho, and unsure if you can answer this, is will that update affect my not stock audio system? I have 6.5 to control but Rockford amp and speakers and wouldn't want it to get messed up.

As Hamah said, software updates are not the same as flashing your HU, which controls eq curve and other audio settings like fade control.
