Might be a wise idea to take your current DVD and make a backup of it in case you don't get it back.

 

Bring it to the dealer, and tell them that your nav is losing the GPS signal, and refer them to TSB EL013-06. Lexus does not allow owners to perform TSBs; your dealer will perform the replacement for you at no cost.

If you want to retain a copy of the original disc, crazy_vag is right, it's a good idea to make your own backup copy before bringing it in. But be aware that more than one owner has damaged the clock panel trying to get it out themselves, so if you aren't good at removing automotive trim you may decide to pass on making that backup. For me, having a GPS that locks 100% of the time is far more important than having the nav override, so I'm really not at all disappointed about no longer having the original disc.

 

Can you remind me how you check the number of satellites that are locking on? Do you recall the difference of satellites that locked on both before and after you got your upgrade?


BTW, Tangfish, yes, the dealer should take care of everything, they'll likely not give you the newest map disc (v6.1) rather your current disc with a firmware upgrade (which should fix your location problem) Curious what new wheels did you get?

 

I enjoy having both

 

Okay, thanks for the tip on the firmware upgrade. Out of curiosity, if I upgrade and make a backup of my current disc, you're saying that I can have the Satellite lock 100% of the time AND still use the override? You're right that I'm not too good with automotive trim stuff, so I probably won't do it, but just wondering.

I got 19" NAD4 Wheels, but just returned them this morning! After all of this trouble, I had to get 3mm spacers to make them fit my IS350 w/ Sport pkg. Then, they rubbed in the inner wheel wells and I finally gave up on trying to make them work (the nav problems didn't help my patience either, though I now know from you guys that this has more to do with software than my wheels alone). I now remember why I stopped messing with aftermarket mods. I thought I'd have new wheels on my car in a couple hours, turned into a 3 week mess and I'm still back on my stock rims!

 

tangfish: Just tell the dealer to give you back your original nav disc... Plain and simple... They have no reason to keep it as they will just throw it away... Tell them you will save them the trouble and throw it away for them

 

Technique, holy crap you are a serious handyman when it comes to this stuff! Can I buy you some beer to come over and hook my IS up?!

 

Trust me, Technique is MORE than up on this stuff! Thx again Technique!
Good luck with your wheels tangfish and keep us posted!

 

If you lived locally, sure... But WA is a bit too far for me to swing by (2700 miles away), hehe...

I'm sure there are some members in your area that could help you though... There are a good number of people on the forum who have helped out other members in their area...

 

With the old software, the easiest way was MENU-volume-top left-bottom left-top left-bottom left, then press GPS info.

With the new software, depress and hold the "INFO" button while you repeatedly flip (about 5 times) the headlight switch between the "off" and "parking light" positions; when the diagnostic menu comes up pick "navigation system" and then "GPS info".

I lock more than double the number of satellites since getting the new software. With the old software, I'd see between two and six, and only occasionally locked the four required to turn on the GPS indicator. With the new one, I see appx. eight (enough to run into the second column!), all of them locked.

 

So, how do I get my current disc out to copy, do I have to take the dash apart or can I just eject it somehow? Also, with Technique's, well... technique, where do you put the DVDs in to watch? I had no idea you could do this!

 

No, if you want 100% nav lock, plus the ability to enter destinations while driving, you need to do the hardware modification (installing a physical switch) that Technique has on his site.

 

Getting the nav disc out: It's a pain... The slot is BEHIND the clock face that has the hazard button... do a search, you'll find many threads on it... But I wouldn't recommend trying to remove it, you'll end up scratching the button/face/dash...

Slot to watch DVDs: same 6-disc changer as your CDs... Provided you have the ML option, it's a 6-disc CD/DVD changer...

 

You need to remove the clock panel, by inserting the removal tools (from the toolkit) in the little holes in the panel, and then pulling the panel out. Once the panel is out, you can eject the disk from the service menu.

Given that several people have damaged the panel, hazard button and other plastic trying to remove it, I wouldn't even attempt it unless you are experienced in removing automotive interiors.

 

Yep, I have the changer but from the looks of your site it seems like a pretty involved process to hack the DVD ability in. Why can't it just be an UP UP DOWN DOWN LEFT RIGHT LEFT RIGHT B A SELECT START like the old Nintendos? Do either of you know an expert hacker/nice guy here in the Seattle/Bellevue area?
