Mine guides were off after the update as well. I turned them on and it's been functional all day. Hopefully it'll stick.Funny you say that, after I applied the update I noticed that my backup camera guides disappeared the first time I used it. Have set it back and we'll see if it sticks... Did notice the updated voice as well. Would love it if there was a release log of some sort for the update.
I think the map update happens automatically. I took a pic of the system info screen where it shows the map database and setup just after I bought it in Jan and noticed overtime it changes.
This is my first time running an update on the radio, but I did see that one component of the update was for the equalizer. I just recently swapped the dash speakers, so I'm not going to be able to give much input on the improvement, since I fiddled with two things at the same time...Ran my update today, not sure but may have improved base in beats audio? Ill see what i feel after more than a couple minutes of listening
TSB details are below.Installed on my Trailhawk last night.
Wonder where I can find the service bulletin details?
