Recommended Car Accessories

I bought the GR-91 GPS radar detector, which requires no wiring, and I also compared the differences with the GR-81.

I need a new GPS radar detector.

I've blogged about it before.The socket-type GPS radar detector from Cellstar is very convenient and useful, as well as reasonably priced at about 5,000 yen."I wrote an article that said something along the lines of.

My husband bought a new GPS receiver from Cellstar, the GR-91, and we have started using it at home.

About GR-91

The new "GR-91" is also a socket type, which can be installed by simply plugging it in with a one-touch operation.

No wiring is required and the compact size makes it easy to transfer the system to another vehicle. It can also be carried with you when renting a car.

Again, theSpeed controllers, speed points, etc. are communicated by "voice" and "Hikari".The features of the system are as follows. As for audio, for example, receiving a GPS signal from a loop coilTwo kilometers ahead, loop coil. Danger. Slow down.It will tell you things like. Then it would warn me 1 km ahead, 500 m ahead, and just before

Camera is in front (right side, left side, etc.), passing speed is ____ km/h

They say.I honestly don't have time to look at the screen while driving on the highway, much less look away from it, which is dangerous, so I really appreciate the audible warning.

As for the "light," the specifications were simpler than before. In the previous version, the glowing part was so small that it was hard to recognize at a glance.This time, the design has only one light in the middle.This lights up "red," "yellow," and "green" to indicate the level of warning content. A quick glance at the cigar socket area immediately reveals the color, so we feel that the new product is still more user-friendly.

Other major new features include

(1) Corresponds to Zone 30
Warns of "Zone 30" (places with traffic restrictions that limit the maximum speed to 30 km/h in urban and residential areas) as published in the Speed Enforcement Guidelines.
(2) Includes points where new control machines are installed
New type of enforcement equipment that can be installed or removed for the purpose of enforcement on residential roads, as well as locations where it has been installed in the past or has been moved.
(iii) Contains areas to be careful of driving on the wrong side of the expressway
Alert people to areas on the highway where they are likely to run the wrong way.

That's what it looks like. Regarding this (3), they actually alerted me the other day when I was driving on the Kyushu Expressway. However, at first"Reverse Running Beware Area."I am not accustomed to hearing the phrase, "What? What? What do you mean, "beware of what? But when I listened to it carefully, I realized that it was a warning against driving in the wrong direction (it can be turned off). (It can also be turned off.) The GPS receiver is of course compatible with the recently popular mobile Orbis system.

Differences between old and new products

Let's compare the new product with the one we used to use at home. First of all, the size is almost the same.

However, the metal part of the plug is a little wider than the metal part of the plug where it plugs in.It doesn't scuff when you plug it in, and it's harder to dislodge."Her husband said.(The earlier ones sometimes came loose when plugged into a 964 or other device, and my husband used rubber bands to keep them from slipping out.)

Incidentally, it could be properly installed on an air-cooled 911.

Regarding the sound, the sound quality is not particularly better than the previous one.(A little muffled, somewhat hard to hear when listening to music or something)I'm just wondering if the color warnings on the light are easier to see... though.New enforcement points are supported, the latest GPS data can be downloaded free of charge every month, and the price is reasonable at just under 7,000 yen.So I think I would prefer to buy a new product now.
