A New GPS Radar Detector

I previously wrote a blog post about Cellstar’s socket-type GPS radar detector being very affordable at around 5,000 yen and incredibly convenient,

and now Cellstar has released a new model called the “GR-91.” My husband quickly bought one and started using it at home, so today I want to share the differences compared to the previous model.

About the GR-91

The new “GR-91” is also a socket-type device that installs with a simple one-touch plug-in.

Since it requires no wiring and is compact, it’s easy to transfer to another car. You can even carry it with you when renting a car.

This model also features voice and light alerts for speed cameras and speed zones. For example, when it detects a loop coil GPS signal, it will say “Loop coil 2 km ahead, danger, please slow down.” It continues to warn at 1 km and 500 m ahead, and just before the point, it says,

The camera is ahead (right side, left side, etc.), your passing speed is ○ km/h.

When driving on the highway, you honestly don’t have the luxury to glance at the screen, and looking away from the road is dangerous, so having voice alerts is very helpful.

As for the “light” alerts, the design has been simplified compared to before. The previous model had a small light that was hard to notice at a glance, but this time there is a single light in the center. It lights up in “red,” “yellow,” or “green” to indicate the warning level. You can quickly see the color by glancing at the cigarette lighter socket area, so I feel the new model is more user-friendly.

Other key new features include:

① Support for Zone 30
Alerts for “Zone 30” areas (traffic zones in residential or urban areas with a 30 km/h speed limit) as published in speed enforcement guidelines.
② Inclusion of new speed enforcement device locations
Includes locations of new portable speed enforcement devices installed or removed on local roads, as well as past and relocated points.
③ Alerts for highway wrong-way driving zones
Warns about areas on highways prone to wrong-way driving.

Regarding point ③, while driving on the Kyushu Expressway recently, it actually gave me a warning. At first, I wasn’t used to hearing the phrase “Wrong-way driving alert zone” and thought, “Huh? What should I watch out for??” But after listening carefully, I understood it meant “wrong-way driving alert.” (This feature can be turned off.) Also, this GPS receiver supports the recently popular mobile speed cameras.

Differences Between Old and New Models

So, how does the new model compare to the one we used before? First, the size is almost the same.

However, the metal part of the plug that inserts into the socket is slightly wider, so my husband said it “fits more snugly and is less likely to come loose.” (The previous model sometimes came loose when plugged into a 964, so my husband used a rubber band as an anti-slip to keep it from falling out.)

By the way, it also fits perfectly in an air-cooled 911.

Regarding sound, the audio quality hasn’t improved much compared to the previous model (it’s a bit muffled and can be hard to hear over music), and the light alerts are only slightly easier to see… but it supports new enforcement points, offers free monthly GPS data updates, and costs under 7,000 yen, making it a great value. So if you’re thinking of buying one now, I’d recommend the new model.
