Harpreet Grover Posted February 2, 2012 Share Posted February 2, 2012 I just bought 2008 RX350. GPS navigation is not accurate to the destination address. It would take you about 200 - 300 feet from the destination and would say "you have reached your destination." How do I make it more accurate. GPS pn my phone works better and also my handheld GPS works better than this car's GPS. Quote Link to comment Share on other sites More sharing options...
The G Man Posted February 2, 2012 Share Posted February 2, 2012 Lexus design it to do exactly that so you can start looking for your destination when the Navi say you have reached your destination. You cannot change it. Quote Link to comment Share on other sites More sharing options...
pj8708 Posted February 2, 2012 Share Posted February 2, 2012 Hi Vicky. Welcome to the LOC. I have had the navigation system do both...say you've reached you destination at about 200 ft. away, and it has said the same when I've been right in front of the persons house. For me, in traffic, I'd rather have a little advannced notice so I can make sure the guy behind me isn't going to rear end me when I slow to make that right turn the navigation lady told me about.

LEXIRX330 Posted February 3, 2012 Share Posted February 3, 2012 Welcome to LOC! Yea that is exactly right. It is kind of odd sometimes mine will be right there and other times it will say you have reached your destination in advance. I agree with Paul I like the advanced notice.

jaswood Posted February 4, 2012 Share Posted February 4, 2012 Automotive manufacturers are not currently, nor in the past, well modivated to provide a reasonable function level of GPS/Nav. That is now changing in much the same way it happened in the pastwith radio/cd/audio systems. For the moment portable GPS/Nav systems have a definite competive edge. And not just because they include lifetime map undating. I have recently had a reasonably long, extended, experience with comparing the perfromance of a recent automotive "captive" GPS/nav with an also current model Garmin handheld. It seemed to me that the garmin would always find the quickest or shortest route much better than the captive system. What was amazing to me was that as I followed the Garmin directions the captive system would re-compute and end up "finding" the same routing, so the "map" resolution, definitions, was apparently the same for both. I can see that the "quickest" routing might be a subjective thing, roadspeed wise, but the shortest should never be. Quote Link to comment Share on other sites More sharing options...
Harpreet Grover Posted February 6, 2012 Author Share Posted February 6, 2012 Does anyone know if there is a software (user interface) update in ver11.1 gen 5 navigation DVD or it just has the map updates? Also if there is a way to have system speak street names. Quote Link to comment Share on other sites More sharing options...
