For the price a Top Radio

Hello there my JVC DVD player has made the car more recently problems I'm looking for a new left. The Sony devices are struck me with App Remote because the super has consulted for me 2-way control for radio and other smartphone around. This all works well, unfortunately, but only if the app is in the foreground and the remote display also. Hence only 4 stars because my SMS messages only be read if the display is on and the app in the foreground. The other settings of the Remote app can only be used when turned on display. I will therefore that is all probably rarely use my Sony Xperia Z since switched display after 2 hours of battery. So if Sony are the Remote app yet thus adapts the SMS messages and read with deactivated display and Lockscreen there is the last star. Would be enough that one could enter as an event when connected to Bluetooth Lockscreen then disable it would work.
