I've just upgraded the RNS-D to an RNS-E in my S4 but there's a couple of things I want to check:
1. When the unit powers up, the bottom half of the DIS shows the compass point letter and nothing else. I have to toggle the stalk button to get range, MPG, etc. Is that normal? I know which direction I'm driving, I don't know what MPG I'm doing!
2. I find that, when browsing through the directories on the SD card, the screen returns to the currently playing directory far too quickly if I stop moving the dial - sometimes it takes more than 3 seconds to choose when you're also trying to drive. Is there any way to increase the delay?
