Another option included on this GLK250 was the navigation system, which displays on the same seven-inch LCD as the back-up camera. As with all recent Mercedes-Benz models, the GLK250 uses the COMAND interface, with a dial/joystick/pushbutton on the console used to select functions and menu items on the screen. This interface, which has menu strips at the top and bottom of the screen, remains little changed from when it launched in 2005. I found the system easy to learn initially, and it has become second nature after seeing it in many different Mercedes-Benz models over the years.
The interface responds quickly, to menu selections, but Mercedes-Benz should consider modernizing it, as the top menu has become crowded. Voice command complements the system, and covers the basics. It let me enter a street address for a destination, showing good voice comprehension, but I had to enter city, street, and number separately.
While driving the GLK250, what really stood out for me was how well the navigation system does route guidance. For each turn, it recommended moving to the left or right about a mile out, then showed useful turn graphics with lane guidance as the turn came up. The voice prompts even read out the street name.
Of course, route guidance also took into account traffic issues.
The maps themselves look good, and show a few landmark buildings as representative icons, but there is no satellite imagery, as found in Audi and BMW models. The navigation system integrates with the Mercedes-Benz Apps feature, which let me look up businesses on Yelp or Google and set their addresses as destinations.
The integration with Google, Yelp, and Facebook, which I was able to find under a little globe icon on the COMAND top menu bar, looks good. There are big, brand-specific icons for each connected service and the data connection is native to the car, which should mean a seamless online experience.
Unfortunately, the slowness of Mercedes-Benz Apps renders it nearly unusable. Each time I tried to activate it, I had to wait a few minutes while it established a connection. Only then could I select one of the services, and each then took almost as long to load. To use Google, I even had to fill out a terms and licensing form, which was particularly tedious. The services available were good choices, but Mercedes-Benz is far behind the curve in online music. There was no Pandora or any sort of Internet-based radio tuner.
Another facet of Mercedes-Benz connectivity is its mBrace telematics system. A more impressive entrant, mBrace includes a smartphone app that allows remote door unlocking and some vehicle tracking capability.
Despite the lack of online music sources, the stereo comes well-equipped with other digital sources. The navigation system's own internal hard drive serves as an onboard music library, and there is Bluetooth audio streaming, HD radio, and a USB port. There is also a dedicated iOS cable, and despite the GLK250's update for the 2013 model year, it is the old-style 30-pin connector. I attached a 30-pin-to-Lightning adapter, then hooked up an iPhone 5 and the system worked just fine, showing my full music library on the car's screen.
Hopefully Apple's fickle and proprietary attitude towards its connectors will convince automakers to simply allow iOS connectivity through a USB port.
As a pleasant surprise, I drove the GLK250 for a week and assumed that the really nice music reproduction was due to an upgraded Harman Kardon audio system, typical for Mercedes-Benz. Eventually looking at this car's option sheet, I saw that it merely had the base six-speaker stereo system, rather than the available Harman Kardon 12-speaker system.
The base system sounded surprisingly clear, with powerful output throughout the frequencies. It sounded very balanced, not too heavy on bass or bright on treble. I was impressed with how well it brought out the nuances of the music I played through it. I would imagine the aforementioned Harman Kardon upgrade would kick up the quality another notch or two.
Going up against the likes of the BMW X3 and Audi Q5, the 2013 Mercedes-Benz GLK250 BlueTEC 4Matic distinguishes itself by being a very easy driver. Where BMW and Audi may emphasize sport handling, the GLK250 feels designed for comfort and ease. The diesel engine adds a little noise and increased maintenance, but its fuel economy is really outstanding.
The cabin electronics fall a little short compared to the high-end competitors, especially when it comes to connectivity, which suffers mostly from slow activation and poor integration with the vehicle interface. However, I was very impressed with the navigation system's route guidance. And although this particular GLK250 did not come with all the driver-assist features, Mercedes-Benz offers a very compelling package. Given this SUV's big blind spots, any driver would benefit from the blind-spot monitor.
