### 1/5 — Doesn’t work. Last update 3 years ago!

*2026-01-10*

This app would be amazing if it actually fn worked. How can a corporation like Yamaha not do a software update in three years rendering these device devices useless?

### 4/5 — UPDATES NEEDED!!

*2025-10-24*

This was a game changer when they released it, but they have fall way way behind with the updates. Need to be able to read XTOs, brand new 4.2 and 4.3s. Come on yamaha we need the update.

Have tested this at our dealer of 15 motors now. No new updates available for this problem 
Just found out today will not work with 2021 F250XCB and have tired with brand new F200  
Have attempted with older F300 and it says failed to connect. Have tried to reach out to Yamaha with no solution

### 1/5 — Will not work with newer 300hp or higher

*2023-06-26*

Have tried with older 300hp Yamahas and it works seems like anything after 2019 it will not connect

### 5/5 — Very nice

*2023-04-20*

Much more convenient than lugging a laptop around.  I just wish it was updated to the newer models more often.
