Fortunately Virtually all non-Harley bike shops that have a flash tool, have a TechnoResearch tool. It’s made by a company called TechnoResearch. All factory Harley flashes are intended to be used for factory Harley speakers and amplifiers and not aftermarket equipment.

Let’s clear something up right away! The factory system that Harley dealers use to flash a radio is not what you should be using. In either case the same software will be used and in either case you should be aware of all your options. The first thing you need to do is decide if you will have your bike taken to a shop to have the flash done for you or if you will be doing the flash yourself. You can find all of our factory radio integration harnesses here. Skipping the correct interface harnesses will result in a bunch of new problems that you don’t need and ultimately amplifier and speaker failures. Always use the proper Harley radio signal harnesses from American Hard Bag so that the radio is properly loaded and balanced, and never use high to low level converters. Now the radio flash will get the best features of your radio turned on but you still need to make the right choices when connecting your new gear to your radio.

Be careful of the blind leading the blind on forums and Facebook.

Be aware that there is a ton of misinformation out there about what flash you should get and who should do it. This guide assumes that you already know what a radio flash is and have some idea of why you need to get one done, but I will explain the details of what options you should program for and why. The following is a complete guide to performing your own radio flash and getting all of the performance you ever wanted out of your factory 2014 or newer Harley Davidson radio.
