It is troubleshooting and time-consuming, and sometimes not successful. ### 1/5 — Scanner will not connect via Bluetooth *2024-06-04, version 1.2.8* Scanner will not connect via Bluetooth. Save your money and buy a different one ### 4/5 — 2023 Review - Firmware Update *2023-10-22, version 1.2.8* Review of U-Scan App version 1.2.8 (126). I have a red Mac Tools branded U-Scan device, from about 2019. Upon Bluetooth pairing to my iPhone 13 running iOS 17.0.3, there was a mandatory U-Scan firmware update. The update proceeded smoothly. As others have wrote, after the firmware update, I had trouble pairing with my iPhone. The U-Scan LED was blinking yellow. I unplugged the U-Scan to cycle its power. Although it was listed on my iPhone for pairing, it refused to connect. At some point in the firmware update process I was instructed to turn off the vehicle’s power. I eventually turned on the vehicle’s power and then the U-Scan quickly paired with my iPhone. Thus, the firmware update instructions failed to instruct to switch on the vehicle power. I had to figure that out myself. The vehicle is a 2020 Ford Transit 250 AWD. I recently had a check engine light. After three restarts the light was off. The U-Scan found and reported the error code and a brief description. ### 1/5 — Disappointment *2021-11-05, version 1.2.8* Good luck getting a Bluetooth connection to the device. If there is a magic way to connect, it is kept secret. No trouble-shooting advice can be found on Actron.com and there are no manuals. It could be such a good tool if only it worked. ### 1/5 — Nearly Worthless *2021-10-20, version 1.2.8* Software is EOL 4 years ago and was hobbled the most basis functions at that time. It’s hard to believe reputable stores like Napa still sell it. If you came her e to get the software after just buying it TAKEBIT BACK! The HT200 I bought at Walmart works great for $50. ### 1/5 — Absolute Garbage *2021-07-28, version 1.2.8* I gave it one star only because I couldn’t give it zero. Once I finally got it to connect it said the firmware needed an update. After wasting a lot of time with three failed attempts it says it can’t be updated. Total waste of my time, don’t waste yours even trying to use this garbage. ### 1/5 — Completely NOT friendly *2021-07-23, version 1.2.8* The app is painful to use, I eventually gave up and bought a different one and their app was very intuitive and user friendly/easy to use. This is garbage, move on. ### 1/5 — Not worth the money *2021-07-05, version 1.2.8* The latest update removed a most important feature; being able to record and display while in motion. I bought device and the new and improved update ruined the device. It is now not much better than visiting an auto parts store and getting scans for free. I consider the marketing a bait and switch scam. ### 1/5 — No connection!!! *2021-03-05, version 1.2.8* I tried several times to make it work but it doesn’t connect with my car at all. ### 1/5 — The item should be U-Scam *2021-02-27, version 1.2.8* Let me start with U-scammers if you are looking for any thing made by this mob keep on moving. It’s a waste of money. ## Frequently asked questions about U ### What does the U-Scan app do? The U-Scan app connects to a U-Scan vehicle adapter to provide smartphone access to vehicle diagnostics.
