The UltraGauge wired and wireless versions are very similar in their capabilities and features.  The table below provides some differences to consider.

	Wired (Ultraguage EM & MX)	Wireless (UltraGauge Blue)
Video
All-in-one	Fully self-contained, all-in-one, purpose built complete solution	Combine the UltraGauge Blue Adapter with your Android/Apple Mobile device and the UltraGauge Mobile Application for a complete solution
Connection	Always Connected	Connects automatically with the mobile device whenever the mobile device is within range.   No user intervention is necessary
Always present	Always ready and always present and becomes permanent instrumentation, just as the vehicle's instrument panel is permanent and ever present.	The UltraGauge Blue Adapter is always present, always active and becomes part of your vehicles permanent instrumentation.  The mobile device need not be present. To access the UltraGauge Blue adapter, either a mobile device can be mounted permanently, or your primary mobile device can be mounted when needed. An older smartphone is ideal for this application
Power	UltraGauge wired is very low power while in use and enters an ultra-low power mode when the ignition is switched off. UltraGauge wired may remain connected without concern for potential battery drain.	Just as UltraGauge wired, the UltraGauge Blue Adapter uses an insignifcant amount of power and is not a concern with regard to battery drain. The mobile device should be connected to a USB power adapter.
Updates	In the unlikely event that an update is required, it must be returned to the factory to receive updates.	Both the mobile App and the UltraGauge Blue OBDII adapter can be customer updated.  As a result new features and enhancements are very common and more frequent. UltraGauge Blue updates, both minor and major, are free for the life of the product
Capabilities	Low cost and efficient, UltraGauge wired is focused on simplicity, with a bright monochrome display which displays gauges in digital text format.	Nearly unbounded future capabilities. Beautiful color, high-resolution displays, allow digital & analog gauges, graphing, icons, advanced graphics and full graphical customization of each gauge. Mobile and Wifi connectivity also allow UltraGauge Blue to receive updates and real-time information
Gauges	Display 4, 6 or 8 gauges per page	Display 1-10 gauges per page. Gauges can be any combination of digital, analog, graphs, or Alert icons
Wired	OBDII cabe provides both power and data connection	Data communication between the App and Adapter is provided wirelessly via Bluetooth. Mobile device power is via the mobile device's battery or via USB. Internet Connectivity is via Wifi or Mobile data
