The Japanese specification 981 and early 991 navigation are genuine and have Clarion navigation.
Originally, the home country specification has a Porsche genuine navigation system called PCM, similar to the late 991 and 718, but only the Japanese specification has such a shape.
981 Boxster's Clarion genuine navigation. The same applies to Panamera and Macan in the early 991 and the same period.
This harmful effect is unexpectedly large, the first is that there is a feeling of retrofitting in terms of design, andAlthough the audio output from the navigation system is digital in the home country specification, ,Japanese specifications are analogThe following is a list of the most common problems with the "C" in the "C" column.
Therefore, theSound quality is a little sacrificed,In particular, BOSE-equipped vehicles of this era have not fully demonstrated their potential.It is.
Also, it seems that the line to the amplifier is parallel to the main power supply of the vehicle, so it is easy to pick up noise, and when the power to the battery increases in sports mode etc., noise can be heard in some vehicles. In the case of IChanged the battery to a lithium-ion batteryLater, I was troubled by the noise (although it was faint).
And this Clarion-made navigation systemAs of 2022, map update support has already expired andI consulted with the dealer, but I couldn't handle it.
Therefore, when traveling all over Japan on a long-distance touring, it is often confusing day by day, such as driving on a road without a road, or conversely urging you to get off at the IC in front of you even though there is a continuation of the road. I came.
Therefore, theConsidering safety, I had no choice but to replace the navigation system.
The conditions considered for the exchange this time are as follows.
First of all, it was very important to be one display audio. For those who are not familiar with display audio in the first place, it is a car audio with a display that does not have a navigation system.
In a little more detail, it looks like a normal navigation system, but it doesn't include the map provided by the navigation manufacturer, and has only audio functions such as radio and Bluetooth. So what about the navigation function?By connecting a smartphone such as an iPhone or Android with a USB cable, the map application (Google Map, Yahoo! Car Navi, Navi Time, etc.) stored in the smartphone is displayed on the display audio screen.
This uses the navigation function.
Use by reflecting the navigation of your smartphone
By using this smartphone navigation app, you can always use the latest map information, so you don't have to pay a high map update fee or the support will expire in a few years like the maps provided by the navigation makers so far.
This merit is very big,Not only can you always use the latest map, but you can also get the latest road information with the communication function of your smartphone, and you are freed from the risk that the navigation system will become obsolete in a few years.The first is the "I" in "I".
And above all, the main unit price is cheap.
Ordinary in-vehicle navigation systems often cost about 80,000 to 150,000,This DMH-SZ700 is around 55,000 yen at the time of writing the blog.
Regarding the design of 2, with this DMH-SZ700, the display part has a moderate glossiness, and because it is a simple and flat bezel, it is judged that you can enjoy the atmosphere close to genuine PCM without destroying the atmosphere inside the car. ..
There is also a 9-inch DMH-SF700 with a larger screen, but this one has a larger feeling of retrofitting, and because of my Porsche usage, the purpose of enjoying entertainment in the car on such a large screen is Since there is no such thing, I removed it from consideration and chose the 7-inch SZ700.
The installation work is done in Osaka, which has a good reputation for the electrical system of high-end imported cars.BESPOKEI asked.

In addition, when introducing this time, we also requested that the amplifier of the main body of the navigation system output sound without using (bypassing) the genuine amplifier. The reason why I made such a request isIn the first place, the sound quality of the genuine amplifier is not good, and it is because of the noise countermeasures mentioned above.
Previously, when I pulled out the fuse of the genuine amplifier, the noise stopped suddenly, so I thought that the cause of the noise was in the genuine amplifier or the line connected to it.
