After initial success with my setup (SPA-DH100 and iPod Touch 4g) I'm now constantly having trouble.
Unsupported apps usually just won't start. The app's start screen loads for ages, and then I'm re-routed to my iPod's home screen.
The only way to get the respective app working is disconnecting the iPod, starting the respective app, re-connect and select the app from the radio screen. Usually this has to be done again after every re-boot of the radio.
I tried this with iOS 5, appradio 1.8.2 and the respective version of appex (this combo worked great in the beginning and then the stalls started to increase), and it is the same with iOS 6 and current versions of appradio and appex.
Does anyone have any suggestions? If provision of more information is needed please let me know.
Thanks.
