Let's start with a bit of a confession. Despite having reviewed quite a few OnStar-equipped vehicles from automakers under the General Motors flag, I rarely, if ever, reach up to press that little blue "On" button while driving. There's just something about asking for directions that just doesn't sit right with me. So, it's a bit ironic that my first major immersion into the OnStar ecosystem happened in a Ford vehicle equipped with the OnStar FMV.
The OnStar FMV ("For My Vehicle") is a universal, standalone OnStar receiver that replaces the rearview mirror of almost any vehicle. Our tester arrived preinstalled in a 2010 Ford Explorer 4x4. We couldn't help but wonder why this particular vehicle had been chosen as our test bed, eventually concluding that GM (OnStar's parent corporation) also sees the irony in having its product installed in a rival's vehicle. There's also the fact that the Explorer's mass downplays the bulkiness of the FMV unit itself. The replacement mirror is downright massive, measuring about 1 foot wide and several inches deep at its thickest point. A large rearview mirror is great for increasing rearward visibility, but may end up looking a bit silly installed in smaller cars.
Along the bottom edge of the unit are a Phone button, the blue OnStar button, a red Emergency button. Along the top edge are buttons for volume control and button backlight brightness, as well as status icons for in-progress navigation, Bluetooth connectivity, in-progress call, and an error indicator. Out back is the unit's internal speaker--the FMV doesn't use the vehicle's speakers like OEM OnStar systems. Finally, an external microphone is installed somewhere else in the cabin; ours was located on the vehicle's headliner.
Tapping the Phone button initiates voice command for calling. Users can make calls using the OnStar FMV's built-in cellular connection or by Bluetooth paring a phone and using the handset's dialer. By saying "Virtual adviser" when prompted, users can also have the unit read out traffic updates, stock quotes, and local weather forecasts. Saved destinations and destinations sent from Google Maps can also be accessed using voice commands here. I like to think of the Phone button as the "Self-service button," because everything that happens under the phone menu is automated by voice commands without interaction with an operator.
The blue On button is the one that most people think about when discussing OnStar. Tapping it initiates a call to OnStar's concierge service, where you'll interact with a real, live person. For FMV service plans, the concierge is mainly useful for helping to find a destination. Just tell them what you're looking for or give an address and OnStar's operators can send a destination to the FMV unit for turn-by-turn directions. They can even initiate a hands-free call if, for example, you'd like to call ahead to make a reservation at the restaurant you're navigating to.
Turn-by-turn directions are given by spoken voice prompts with text-to-speech pronunciation of street names. Voice prompts, like hands-free calls, are heard through the unit's internal speaker. Even at its loudest, the internal speaker is only about as loud as your average portable navigation device. So, if your vehicle generates a lot of road noise, like our Explorer, or you're also playing music though the vehicle's speakers, you'll have to listen carefully, so you don't miss a turn. In the event that you do miss a turn, the FMV has a limited capability to reroute your trip, but if you get too far off course you may have to manually re-initiate routing.
Knowing where to go without the visual feedback from a map took a lot of getting used to, but it wasn't so difficult that we couldn't manage. On one or two occasions, after missing a turn, we were instructed to return to the route, which was harder than it sounded without a map. In those cases, we elected to just restart the trip with a call to OnStar.
The third button is for Emergency services. After tapping it, you can summon medical, fire, or police assistance, report an accident, or, if you're a good Samaritan, summon help for another motorist. If you need non-emergency help--for example, a tire changed or a tow truck--the standard OnStar concierge can dispatch Roadside Assistance. Automatic Crash Response summons emergency personnel if the system detects an accident and the user is unresponsive to a call from an OnStar operator. For obvious reasons, we did not test this functionality.
Core OnStar functions that are not supported by the FMV include Vehicle Diagnostics and Remote Door Unlock. Also, although the system is able to track a vehicle reported as stolen, FMV is unable to stop the car.
Many are no-doubt wondering why we didn't have the FMV unit installed in our regular test car? We were told that our 2007 Chevrolet Aveo was incompatible with the OnStar FMV, which was a bit of a black mark on the universality of the FMV, but, to be fair, we've experienced issues in the past with the Aveo's compatibility with certain OBD devices, so we'll chalk this up to a "car issue" and not an "FMV issue." You can check your vehicle's compatibility before you buy on OnStar's Web site.
The OnStar FMV retails for $299 and requires professional installation, so go ahead and figure an extra $100 for labor. Owners will also need to subscribe to the OnStar service, which runs $18.95 per month or $199 for a year. At that price, the FMV competes directly with the newest batch of connected portable navigation devices, which do a better job of guiding drivers from point A to B for people who like to search for their own points of interest. But if you like the idea of having a real person on tap to help you pick destinations and a safety net of roadside assistance and emergency services always available, OnStar FMV may be worth consideration.
