Map Data Issue
I'm having some issues with my map data when i start up my car. there has been multiple times when i start up my car and touch the accept button for the warning sign and then it say's "unable to read data please contact dealer" then i'll turn off my car and start it back up and try again. sometime it works after one try but sometimes i have to do it 3-4 times. i notice it only happens on really cold days. i don't know if that would make a difference but does anyone have this problem? i have the bypass system in my car, u think that would do it? i have a 07 ls, haven't upgrade my navi. any help ?

Wiring harness issue (loose or may need to be replaced) or bad hdd.
If it's the latter, expect the matter to get worse (frequency and how many times it takes to get it to work when it happens). If it's the former, then I wouldn't be surprised if other things started to fail as well (radio, ...etc).
Either way, you better have it checked by Lexus. Warranty?
You may also want to get into the secret menu (dealer's menu) by pressing DISP, then upper left corner, lower left, upper left, lower left. That will get you into the outer secret menu.
You could so get into the inner secret menu by entering in the outer secret menu then upper left, lower left, upper left, lower right.
In there you'll find many testing & diagnosis option. That might give you a hint?

My '08 does not have the accept screen. However, when the car was about 9 months old, I got the same message when starting the car. It happened a few times and I called the dealer. It turned out to be the hard drive, which was replaced under warranty.
Since you have the bypass, you should definitely check all the connections first. If that does not fix the problem, I strongly recommend removing the bypass before taking the car to the dealer.
The bypass is not a Lexus authorized item. They could claim that the bypass caused the problem, because it was directly connected to the Nav system. That would be a valid reason for them not to repair the Nav under warranty.

Obviously you can remove it if you want to. That would 100% tell you if the problem is related to the bypass. But if you don't have to take it out, why bother?

The new hard drive has the same map version as the original one. Remember the car was only 9 months old when they replaced the hard drive. Perhaps the next version of the map was not yet released.

when you told the dealer that you had the bypass system they did not say anything that it was the bypass system that was causing the issue ? i just don't want to take it in and they say that its not going to be covered under the warranty due to the bypass system.

if you had installed Nav bypass your self, then it should only take you 10 - 15 minutes to remove it. I think jstjohnz simply got lucky with his SA and a tech at the dealer. I personally would remove it and not take my chances, but it's up to you.
