Ratings and reviews

Edit 09/11: App updated Nov 2025. STILL CONTINUES TO FAIL TO CONNECT VIA BLUETOOTH. Yet I have no issues connecting to any other devices. Still 💩💩👎👎🤡🤡. New Google Pixel 8 phone. Continually fails to connect via Bluetooth. Yet, older Pixel 5 has no issues. No app updates since 2022 which is nearly 1 year before the Pixel 8 was released. Customer service is USELESS. VERY POOR.

Since the recent update I can no longer connect to the box. Never had an issue with connectivity before but now it's just loading continuously 😟

90% of the time it doesn't connect, ended up having to jump out in the rain to adjust it under thr bonnet on the device Edit. Unfortunately I can't get it to connect at all. Pretty unacceptable for for an expensive optional extra. The product itself is great but I think I'll advise people stay clear of the bluetooth option as I feel pretty scammed out of the extra money. Update. Dyno showed it wasn't even doing anything, app never once connected. Paid for a remap isntead, huge difference
