Would love an option for CarPlay to display live data, etc. ### 5/5 — Super application pour jeep wrangler *2026-07-10* Encore merci pour cette superbe application très efficace et indispensable pour tout les possesseurs de jeep mais si pouvez la traduire en français et compatible avec car play pour l’avoir directement sur autoradio ça serait encore plus génial merci par avance **Developer response:** Send us message on OBD JScan Facebook page and we will try to helpy you with that problem. ### 4/5 — 2026 Ram 1500 RHO *2026-06-13, version 15.43* I have used this app for for previous Jeep and it was great. I now have a RHO but there is no support? Any idea on an update? ### 3/5 — Language *2026-06-12* I don't understand why you still haven't put French ### 5/5 — Bueno *2026-06-10, version 15.42* Excelente ### 5/5 — Great price great program *2026-06-06, version 15.42* Successfully flashed ABS module vin. Also successfully completed ABS initialization. ### 5/5 — Very cool *2026-05-11, version 15.41* I really like this app. Used it on a JK and now on my JL 4xe. Wish it was CarPlay compatible… : ) ### 5/5 — Great App for KL Cherokee *2026-05-11, version 15.41* Got this app to use with my Vgate MC+ on my 2016 Cherokee. Works great! I changed my infotainment system and was able to do a proxy alignment without having to take it to the dealership. I did unfortunately try to disable the stupid stop start. But it also disables the remote start. When I changed it back, something happened and now there’s a p1500 permanent code for the VSS. It’s supposed to go away over time after relearn. No check engine light associated with it though. Hasn’t affected anything. Would like to see a backup option. If there is one, I couldn’t find it. ### 5/5 — Very handy app *2026-05-06, version 15.41* Very useful for diagnosing issues with your Jeep,dodge,Ram. Will save you $$$ to find errors rather than pay a mechanic to To the same task, there are plenty of sites online to define each error code and what it relates to as well as how to fix it. ## Frequently asked questions about OBD JScan ### What does OBD JScan do?
