The Dynavin is indeed the best looking option (I have it installed) and it is OEM in look BUT and a big BUT. The display is unreadable in bright sunshine. The Garmin option will not have this issue. So if you live in overcast weather year round then yes the Dynavin is OK but otherwise the Garmin where decent LCD display technology is used.
