I have watched tons of videos and the app just does not contain the settings every single HP tuning video claims should be there.. It won't update my RTD 4.when connecting and there is no option in settings to do so like they claim. I can get the app to connect to the device but it won't download the stock file. It errors out and light goes red and just gives the error "no connection read". Been waiting for a response from Tuner and HP tuning.

TDN app on my Android won't connect to my RTD+ via Bluetooth. It has worked in the past. Thankfully was able to connect on my wife's iPhone to upload a tune to my car. The Android app needs an update to support the RTD. Edited

It kind of worked a couple times, then failed to connect VIA bluetooth. Nothing I can do to get this garbage to work.
