Car play

We need car play support please

App keeps showing in Mirror image

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.

Really useful

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!

Doesn’t work

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.

It works, but it’s lame.

Giving this a 2-star rating because quite frankly for the price it’s very disappointing. It does what it’s meant to do, yes, so it’s functional. But the interface for settings is crappy, there are UI glitches (i.e. can’t see the rpm limit value), it often crashes when I change my map, and honestly... my biggest complaint is, for the price... make this compatible with Apple Car Play! It’s literally a car app, and we all know it’s illegal to use our phone while driving, so this app is literally asking us to not follow the law in order to use it. I’ll gladly update my rating if they either give it support, but until then I find this app overpriced... but then again, that’s what happens when there’s no competition.

CarPlay support

I’d really like to see CarPlay support added as well as an updated, cleaner UI. Works well though sometimes it’s finicky to get connected. Still insanely convenient to switch maps on the fly. The connect kit really is a must have for any jb4 owner.

Great app

The app works well and connects on every launch. Wish it read more codes on the Infiniti’s

more optimization

Needs more iphone x optimization
