I hope someone can offer some advice on this. I've installed the bluetooth on my car, I have a RNS-E with the latest software installed. The satnav sees the bluetooth, i can make calls and it's all fine. I have a few issues though, I have a MFSW and when I press the left button to scroll through the numbers, it's on a limited time. After about 3 seconds of scrolling it goes off. Also, I cannot enter 77 on vcds. It says no controller installed. Any advice welcome. No fault codes showing on the rns-e either.
