1. Brand new (under 200 miles) 2020 EXL, when I put the car in reverse the map guidelines occasionally disappear. Tried changing settings from dynamic to fixed but no change. 2. In addition, when I adjust sound settings the TREBLE slider doesn't work, my 2012 EXL had a very robust sound system equalizer. 3. Has anyone found a list of phones that are FULLY compatible with Handsfreelink without using carplay. My iPhone 11, can read but not send texts. Anyone have all the functions working?
