When my Potenzas wore out around 20K I switched to the Michelin Pilot sport PS2's and I absolutely love them! They are way quieter, they seem to roll easier, they are wearing nice and slowly (estimating 25K out of them before replacement) and they are more responsive IMO. The Potenzas were not a bad tire at all but they got awfully noisy during the last 5K or so before I dumped them.

I've got an 07 and mine came "XM Ready". I thought that I could just subscribe but the receiver and some other components were not installed. The antenna was there. I got the instructions from a post here, purchased the missing parts and installed them myself. The dealer quoted me 2 hours to do the installations.... I did it the first time in 45 minutes start to finish including clean up. If I did it 2 more times I'm sure I could do it in 25-30 minutes. Its real easy, you just need to understand how all the different upholstery clips work. They are clearly the most challenging part.. that is: not damaging anything during the process. My advice to anyone with the "XM Ready" configuration, buy the parts and do it yourself. Its really easy. Actually, everything you'll need is in this post. http://www.clublexus.com/forums/showthread.php?t=297124

OK.. I bought an 07 IS250 from JM LEXUS in Florida in January. It came prewired for XM. The car does NOT have Navigation. The car has a "Shark Fin" on it's roof. I reciently purchased and installed the OEM XM tuner and fit kit and the shark fin IS FOR XM RADIO! There is a wire I found during the installation that connects to the XM tuner. It is the antenna wire. It hangs from the metal framework behind the passenger side trunk liner. It was wraped in some soft foam tape and a tie wrap. The antenna connector and harnesses will NOT work with a Sirius tuner. The installation was quite simple and went without a hitch. Took me 45 minutes start to finish. Radio works perfectly and it is exactly how the owners manual describes the function of the sat function. I feel like it was a great investment at $280.00 plus 45 minutes. Dealer wanter $980.00 to do it. Said it would take 3 hours. Guess the listen to nice music for 2 hours and 15 minutes on my dime :) I'd like to try to clarify this a little. You will have to purchase the OEM XM reciever from a Lexus/Toyota dealer. Hence the OEM part. The XM recievers that are readily avaliable at Circut City and Brands Mart will NOT connect to your built in antenna, nor will they interface with your factory radio. Even some dealers it seems are installing lower cost XM recievers that require mounting an external antenna on your windshield next to your rear view mirror. Wires are run under the lip of your headliner. Worst about the non-OEM XM recievers is that you will have to have an external tuner, that is to say that you will have to have a small display head mounted on your console somewhere. Please feel free to ask me any questions in PM

Hey, after reading your post in My.is, I ordered those parts and installed it. Was so easy !! Took me 45 minutes and went exactly as you said. Thanks for the advice and good job with the info and pics !

If you order the XM radio from Lexus, all you have to do is read the instructions...and yes the labor charge is a bit excessive for anyone with some time to spare and the ability to read.. B) I'm new to this forum, found it looking for information about installing the XM TUNER in my 07 IS250. This file may be helpful to anyone looking for the same information. It contains part numbers and detailed instructions for installation. I will look for the parts online and make the installation myself within a few weeks. I'll post again after I install. http://www.lexus-parts.com/IS_XM.pdf Hope it helps.
