Updates for Lexus or Toyota usually become available during the fall, so it’s best to be aware of the release timing. Most drivers will not experience a significant mapping change with an update so most people do not need to update the Navigation map every year.

The Lexus Navigation DVD version 7.1 will upgrade the following cars of Lexus and Toyota.

Have you ever had the experience of happily driving along, confident that your radar detector is on to alert you of cops on the look out for speeding motorists, only to be jolted out of your blissful enjoyment of the ride by being pulled over for speeding? The sad fact is that most of the radar detectors that are in the market right now are not all that they are touted to be. Further, cops now use new models of radar guns and that is the reason why your radar detector failed to do its job.

The police utilize radar guns that have digital signal processing (DSP) technology. DSP allows the radar guns to constantly be on just waiting to read a cars speed. This allows radar guns to measure the speed in less than four tenths of a second. You have absolutely no hope of stopping in time to prevent a speeding ticket.

These new radar guns are not only fast, they also have a lower power foot print. They use Ka band frequency and a very high bandwidth. This is five times higher than what was used by the earlier X band radar guns. Now you know why your radar detector is unable to spot these new radar guns.

Now, detection signals can work anywhere in the spectrum available, and a radar detector isn’t sure which will come at it. So it has to scan the entire length of possibilities, which takes time and reduces detection range, which means that they become less effective.

Another advantage the police have in regards to their radar guns is the guns ability to detect the highest speeding vehicle within its range. This is unlike the old radar guns that had to measure each cars speed individually. So no more hiding behind a larger vehicle to avoid detection of your speed.

There is more bad news for you if you always tend to drive fast. As the old X band radar guns go out of use and are replaced by the latest model radar guns, the radar detectors will become less and less effective.

Its time to start researching the new improved radar detectors that are available. When doing this research it is important to know where most of your driving occurs, whether it is on the highway or in the city. City driving requires a radar detector that is able to filter out all of the other frequency information while still being able to detect police radar.

Ultimately you must realize that your choice of detector now will have to be updated as the radar guns technology is improved. You will also have to realize that no matter how great the radar detector is, it is simply not fool proof.
