Thanks for your reply. I will place my order for the F-Sport intake then. Have you noticed any improvement in performance since you installed your F-Sport intake?

i got this annoying vibration too. on rough road surface it just starts buzzing. if i press in the wire or something from the back it stops until i let go and it comes straight back. when you say you split open the mirror using a flat trim tool, can you explain it a bit further? did you actually take the mirror out of the main housing? if so how is it actually attached to the main unit? clips? thanks

I've read alot about the F-Sport Air Intake system available in the states. I'm wondering if this would fit UK specification IS250's. and if it does what will be the service requirments? if i take my car to the dealers for a service they wouldnt be able to change air filter as this would be an F-Sport one. How often does the air filter actually need to be changed?

Aerial location is not a problem at all. If you store your DVB-T Tuner in the glovebox, you can simply run wires from behind, along the side of the car (under Illuminated Door Sill) to the back beneath the windscreen.

thanks for all your replies. i am looking at getting autosol now. i looked in halfords and they have two autosol products 1st one is Autosol Chrome Polish 75g and the 2nd one is Autosol Chrome Cleaner do i need to get both of these? and use the cleaner first and then use the polish?

anyone have any tips on how to clean the two tailpipes on the IS250? they are shiny chrome but mine has got dirty and looks rather dull now and has lots of road tar.

just an update on this issue: my car was in for a service at Lexus Woodford and i mentioned the startup crank/rattle. They insisted that the noise has to be replicated and booked the car in for 2 days. First day was for the service and the second day to try and replicate this noise. I took a copy of the US TSIB with me but they didn't want that because apparently the cars in the states are slightly different and the TSIB's don't always apply. anyway, luckily i think they were able to replicate it as after 4 days now they have told me that they have ordered the parts for it after liasing with lexus GB. I've got a list of the parts that are on order and these seem to match with the part numbers listed in the US TSIB except for one part. It seems that Lexus GB now has an official TSIB on this issue. So if anyone has experienced this issue i would recommend a visit to your dealer.

theres plenty of space to put the tuner in the glovebox

how can you possibly even get the dealers to look at it if its so intermittent. dealers are just so reluctant at looking into it if it cannot be replicated.

yeh the double DVB-Tuner is what you need, the cheap ones on eBay are no good, i made the same mistake in the begining which was a waste of £40. the stick on aerials should be the booster aerials that have a power connection to them aswell. This is sufficient for me and have had good reception. Hope that helps.

thanks for that info Purvesh. although i am not having any reception issues, i might give those antennas a go and see what signal strength i get. do these Alpine antennas also require power?

tuner is in the glovebox and the aerials are located at the bottom of the rear windscreen (one on each side)

You have a genuine complaint regardless, but the TSIB is proof that it's a recurring problem that Lexus have recognised and have a fix for. No way can they knock it back. problem is most of the time they want to replicate the problem and as it is an intermittent problem its quite difficult. apparently there's a metal pin that locks the cam position when you shut the engine down. If the pin fails to engage (old design), then you get the noise on start up. The pin retracts when the oil is up to pressure. All you are doing with oil changes is reducing the amount of time it takes to pump up. You're not solving the fundamental problem.

I have the same, does the fact that this TSIB from an american website matter? can i still present this to the dealer?

Heres the steps i've got from another thread: Little tricky to do though 1) find the "in car tools" in the trunk, in the tire jack kit which fits next to the spare. They are easy to miss. 2) use the rods to push back through the holes. Use lots of force. 3) this will loosen the clock display. then you'll need to jiggle it and pry it off. 4) then eject the old map dvd. 5) turn car off. 6) remove fuse #4 (TV.1 or something like that) from the fuse box right above the parking break pedal. 7) turn car on. (it'll complain in english and japanese that the dvd can't be read.) 8) insert new map dvd (in my case the patched 7.1 with 5.1 loading.kwi file). It will take a minute to load. 9) put clock cover back on, and you're done. The hardest parts are: 1) finding the "in car tool" picks; 2) prying the clock display off; 3) prying the fuse out of the fuse box. Remember, all your stored nav info will be lost when you do this - you're starting from scratch again. You need to put the #4 fuse back in before you turn the car back on. Not that any of you wouldn't figure that out. Also found that a small pair of needle nose pliers worked best for pulling the fuse and then you can use just your hands to put it back in. Oh and one more thing. Do NOT use a DVD with a self-applied label. It will heat up and start coming off and potentially ruining your NAV. Good luck!

I believe it's located behind the panel that has the hazard light switch and time on it. There are two small pinholes on either side of that panel. There is a tool in the Lexus toolkit in the trunk that goes into these pinholes to open the cover and change the DVD.

i'm 25 and have a 250 SE-L, i've had it for about a year so far.

let us know what they say chandru, if its something that needs looking into then i'll have to call up my dealer aswell then

not sure if i'll be able to come, quite a busy schedule next couple of months. near Hainault

I suppose reception does vary from place to place but so far everywhere I have been have had very good reception with this double DVB-T tuner. In the past i used to have a single tuner and that was useless, as soon as I used to move off it would cut-off. plus the amplified antennas helped me alot. I used to get terrible reception at first with the single tuner.

Here is the cost outline and links: Costs: Order #1: $416.87 Including Delivery 2x Headrests with 7" TFT 2x Amplified Booster Antennas (ANT-350A) 1x Double DVB-T Tuner Order #2: $429.98 Including Delivery 1x NAV A/V Module Converter Including the bits and bobs of phono plug connectors, soldering bits and wire leads from Maplin and heavy duty Velcro from B&Q, the setup cost me just under £500. Links: Order #1: Purchased from a wholesale supplier in China that sell VCAN manufactured products at very reasonable prices. When I placed my order they had special offer prices on the headrests and the DVB-T tuner. I purchased headrests at $74.70 each. It is now priced at $93 each. The one i purchased is kind of the cheapest headrest in their range but seems to be the only one that matches my lexus leather perfectly. The link for the headrest is: http://www.onvon.com/tm705h-inch-headrest-monitor-p-30.html The Double DVB-T tuner cost me $124.20 but is now priced at $145.00. The link for that is: http://www.onvon.com/dvb2008-digital-receiver-p-100.html The amplified antenna is still the same price at $22 each, and the link is: http://www.onvon.com/ant350a-digital-antenna-p-106.html Order #2: Purchased from eBay US member (ID: cardemand) link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...em=220223208019 I must say I was very impressed with delivery service by both of these suppliers. The order from China was dispatched On Friday late afternoon UK time and I received it on the Monday. and the US order was dispatched on a Wednesday and I recieved it on a Monday aswell. I hope this cost outline helps. I'll be happy to answer any questions anyone may have. Thanks Pics of the Items ordered are below:

ok firstly, here are some of the pics I did manage to take, and will be posting guide shortly. Centre Console Area Removed for Access: Nav Screen Unit Put Back together after installating A/V Module/Converter. Notice the two sets of RCA's coming from the SatNav. This is the A/V 1 and 2 which I extended to inside the glovebox. I actually made the RCA extensions using the cable and solder plugs to make the exact size and prevent rattles. Also used alot of sponge like insulation to prevent rattles. Glovebox Compartment and Knee Airbag Removal Behind the glovebox compartment Knee Airbag Unit Inside the seats from the back to connect the wires

Sorry for the late response been quite busy since i last posted. Anyway, I will try and reply to all your questions below: As I was too busy with the installation itself I didnt get to take much pics, however I do have a few camera-phone pics that I will post in a little while after downloading from my phone. And in regards to links and models, I will post back a detailed guide with the equipment I purchased and costings and an explanation on how I did the modification. The monitors are 7". The monitors come integrated into a leather headrest as I did not want to cut out my originals. I've stored my originals away in the storage. At first I bought 9" ones on eBay but the leather on that wasnt a match with my black leather on the lexus and plus one monitor was faulty as it used to have some issue with power and cut-off. I got rid of these on eBay and then purchased the 7" headrests directly from a wholesale supplier in China who were very good and provided a very fast service, and I was able to get them to confirm that the leather will match. Leather matches nicely now and it doesnt look out of place (actually people think its OEM). Anyway, in my next post with the guide I will provide further details on these screens. I got the NAV Converter that you posted the eBay item number of below. This unit is full plug and play so no need to cut any wires or anything. I did quite a bit of research and all of these plug and play units seem to actually be made by the same manufacturer but very highly priced with many companies selling them. The cheapest is sold by ebay user "cardemand" with delivery to the UK it comes to a total of about £250 and it is a nice compact unit. Sure I will post links and details of costing etc on my next post of the detailed guide. And yes sure I will take video of car moving and the DVB sometime in the next few days, as i cannot do it myself. (need to keep my hands on the wheel :) ) I'll be posting a detailed guide in a while with a very few pics i managed to take. Hope it will help.

yeap I did all the mods myself and the mod is the exact same for all Second Generation IS. The DVB-T Tuner i bought was a double DVB Tuner by a company called VCAN. and I have two amplified antennas situated at the edge of my back windscreen and is wedged in. It cannot be seen from outside as its just a small strip style antenna. I put one on each side.

I have recently completed my NAV Mod on my Lexus IS 250 to cater for rear headrest entertainment system. I have two A/V input sources now available on my NAV screen using standard RCA cables. I have setup a Double DVB-T tuner for the first A/V input and the second A/V input has been plugged into a SlimLine PS2 with wireless Controller Pads. This is all viewable on the SatNav screen aswell as simultaneously shown on the rear headrests. The headrests also receive DVD Video Playback from Nav DVD Unit, which has also been hacked to provide DVD playback on the move. I have taken a brief video on my camera phone showing the reception and quality of the DVB tuner which was tuned into BBC News 24. Reception has been tested on speeds upto 75mph with excellent reception and with no picture loss. However built up areas can affect reception.
