ADS-MRR vs. ADS-MRR2

For starters, when you receive your Soundstream radio, your ADS-MRR or ADS-MRR2 will be pre-flashed/programmed for your specific bike and 100% ready to install in your bike. But, if you want to update your module or reprogram your module in the future, there's a distinct difference in how that's done depending on the module you choose:

Flashing/Programming your Maestro module: 

• ADS-MRR: in order to flash or update your module in the future, you'll have to remove your fairing, disconnect your Maestro module from the harness and connect your Maestro module to a computer to download the newest update to your module. 
• ADS-MRR2: you will be able to update your Maestro module via bluetooth by downloading and wirelessly connecting your phone to your module via the WebLink app, found in the Apple App Store and Google Play Store. This saves you the from having to remove your fairing to complete this process.
