@mark_taba85: I found it while perusing a mazda3 forum. For the most part, people liked it...but as with everything, people also had complaints. Eonon is the only company that produces an OEM aesthetic touchscreen nav unit like this. It appealed to me because I did not want to draw attention to would-be thieves while upgrading the stock HU significantly. But then I found the Z.
@Wicked CAS: from the few complaints that I saw, people claimed the UI controls could be a little laggy at times.
