Apple has included 3rd party navigation application support for CarPlay with iOS 12, which means the cars equipped with CarPlay can use maps other than Apple Maps as long as they make use of the new API. Google Maps and Waze were named when the feature was announced back in June, but one of the major Internet Service companies in Korea, Kakao, beat them to the punch and launched the CarPlay-supported version (3.26.0) of its Kakao Navi app today, September 15. As the iOS 12 GM was already released to the developers and beta testers two days ago, it was possible for me to try it out on my Bolt EV as you can see above.


Kakao Navi is no stranger to the car navigation game, as it was selected as the sole navigation app when Google's Android Auto was launched in Korea in July 12 of this year. This happened because the stand-off between Google and the Korean government resulted in a severely crippled Google Maps support in Korea. In any case, Kakao Navi has claimed first 3rd party navigation support on both Google and Apple's car interfaces for Korean users.

After arriving in Ulsan and charging the Bolt EV's battery as seen in the last post, my four-member family went about our own business for a couple of days. When it was time to return home, we dropped by a nearby Costco to pack up some items in the trunk. While the space was smaller compared to the one in the cars I used to drive, we were able to fit everything in.

We spent 18% of the battery charge during our stay, leaving 76%. It seemed a bit risky to attempt a full return without a mid-trip recharge since the previous trip used 73% of the battery. Still, I thought it presented an interesting opportunity to see the car's limits and pressed on casually, with the air conditioning on. The following time-lapse video shows what happened in its entirety.


As you can see, the Bolt EV was able to return to the charging station in the parking lot at home just barely. Like the previous trip, this sort of drain-to-the-bottom run should be attempted only if you're sure of the range and the charger is ready at the end. So what was the scariest moment?

It’s been more than a month since I started driving Bolt EV. The lack of any engine noise, as well as the responsive acceleration and regenerative breaking continue to impress even now. I felt that the car definitely belonged to the 21st century and was glad that this was the first car I bought. Driving experience aside, many still wonder and ask if the car is truly good enough for a long drive and whether the charging speed was any good. This is where showing the experience would be better than explaining.

Here is the video of my recent cross-country round trip with Bolt EV in time lapse mode using the setup you see in the photo above. It should be noted that the Korean Peninsula is only about 300km wide and the South Korean part is about 400km long. Therefore the “cross-country” isn’t on a such grand scale here. Still, the range of Bolt EV (383km) implies that it could go almost anywhere in the country with a single full charge and this is important for many potential buyers in Korea.


On the video, Bolt EV took on the task of taking my family on a routine trip to my parents’ home at the opposite coast. This trip from Naju to Ulsan covered a distance of 302.8km, of which more than three quarters were on the expressway. The day was warm and humid (more than 25C on average, with a bit of rain) and so the air conditioning was running, yet the car nevertheless passed with flying colours with plenty of margins to spare. We started out with 91% charge, and still had 18% left after reaching the destination. Let's see this in more detail.

I have been a long time user of a FLIR ONE, an infrared thermographic camera module that connects to a smartphone. This type of camera visualizes the hot and cold spots of a subject by measuring infrared emissions. Such cameras are generally quite expensive, but by reducing it to just the camera module and relegating much of the operation to the connected smartphone, having it at a much lower price point became possible. That's how the FLIR ONE series came about.

More specifically, I own a first generation of the series, which is shaped to fit on an iPhone 5 or 5S only. Subsequent generations were redesigned to support a wide range of phones. So I was quite thankful to have given the chance by FLIR to test out the high-end version of their latest generation smartphone attachment - the FLIR ONE Pro. I was eager to see what sorts of improvements were made during the past few years.


The product came in a colourful box that contained the main module, a USB-C charging cable, a compact carrying pouch, and some leaflets. The general style of the packaging had remained constant and professional, and the addition of a pouch was a nice touch since the module really shines when it can be brought to everywhere.

The quick start guide basically tells you to connect the module to your smartphone and install the FLIR ONE app. It is really a plug-and-go affair, so the simplicity is understandable. I do wonder if basic app functions could have been explained on paper a bit further, however.


Comparing to the first generation module, the look of the main component - the thermographic sensor and the regular camera bundle - hasn't changed much. However, the overall packaging has changed dramatically. The first generation was shaped to encase an iPhone 5/5S, so the long shape allowed it to house a large battery. It also has a recalibration / power switch next to the sensor bundle.

The FLIR ONE Pro, on the other hand, was designed to fit on a data/charging port of a phone and is smaller than a transit card. In order to accommodate thick phone cases, the length of the connector on the module is adjustable through the dial just below it. In order to make it compact, however, the integrated battery is much smaller and runs shorter than the first generation. There is a small power button at the bottom with status light. Automatic recalibration function did away with a need for a manual button.
