Well, I received my unit last week and installed it this week. The unit is great, built well, easy to install, and the messages are clear. I used 3m molding tape to attach both heads.
The message about the sunlight is cool at first, but with winter coming it becomes annoying quickly when it goes off 5 or 6 times during your drive home. Ivan I know you are working on the ability to customize the messages and this is one I would love to be able to turn off
In terms of questions, I am nervous that the heads will fall off as they get wet or snow on them. Is that tape pretty reliable as I would hate to have one fall off and end up in my radiator. I also found the tape really stuck to my plastic grill but did not seem to stick as well the the LI head.
