It would be good to have new versions supported iOS 10.* !!!!! Thanks!!!!!

on the iPhone x “preview logs” don not closed. Please correct.

Love JB4 and everything about it so far, with the new update I cannot seem to retain connected to my device. I’ve reconnected everything and reflashed but still has not changed anything

We need car play support please

Not sure if anyone else is having an issue, but I have to keep deleting the app and reloading as when I turn on it keeps giving me a backward or mirror image. Will update rating when this gets figured out. I’m using an iPhone 14 pro max.

It's a must if you have the JB4. I use it daily to clear codes or change the map settings. When I had issues, technical support was awesome everytime. Thanks for the good work guys!

I install it with the wireless app with iPhone 11. Worked few months and I tried to change map for valet and since, the app doesn’t work. I tried to update and it’s even worse. The car don’t want to go faster than 20 miles/hr. And check engine is on. I’ve tried every things on n54tech. I delete the app and the firmware cannot download. I don’t recommend. I cannot connect the wire the car don’t go. I bought it for notting. Its big waste of time and money. A good mecanic order it and installed it. And when he order the wireless kit, they sent the bad kit for my car and had to complain seriously to get the good kit. Never again for me.
