Ls430 Roof Antenna

[Jazoo]

THE ANTENNA MAST ON OUR RECENTLY PURCHASED 2006 LESXUS LS430 IS MISSING. DOES ANYONE KNOW THE FUNCTION OF THIS ANTENNA?

WHERE COULD I FIND A REPLACEMENT ANTENNA MAST @ REASONABLE PRICE?

THANKS

The mast is for the GPS system that the nav system uses. If you don't have nav, you don't need the mast. You can find the little masty piece several places--just google "Lexus LS shark-fin antenna" and you'll find it.

Wrong!!!

The nav antenna is under the dash cover, so hope you never have to change that. The mast is only for the earlier version of lexus Link, which is no longer supported in any case. Some of the parts sites list replacement antennas for about $100. I hoped I could use it for satellite radio, but turns out that requires an antenna with an LNA and the simpe mast will not work. Therefore, I simply unscrewed mine and put a stainless steel screw in its place because I didn't like it there in the first place. Note, I do have the nav system and it still works just fine. The info on various antennas and functions can be found in the factory manuals on techinfo.toyota.com.

i have a 2004 LS430. The little stubby antenna broke off from the box above the rear window. The nav system and the radio still works. What does this antenna do and is there a reason to replace it?

The roof antenna was used either for a dealer installed phone system or the obsolete analog Lexus Link service. Replace it only if you want it to look pretty or you could use a little metric bolt to plug the hole.

Although I do not like the look of the antenna base on the roof, I will just leave it alone.

Thanks!
