For those of you who own an iPhone but don't have Tire Pressure monitoring system on your car, here's a neat solution that uses your iPhone as the display.
It's just been released in Asia but seeing as I fly to China on Monday I'm having one delivered from Taiwan. The BT module will be plugged into the switched 12v supply in the boot of my car since I don't use it anyway.

I've already down loaded the free App from iTunes and apparently this works on all iPhones, iPads etc without Jailbreak.

Looks good but Id prefer the LBD tyre girl in attendance  Now - MY11 RRS Autobiography TDV6, Orkney gray, tints, steps, daylight running lamps and allllll the toys!!!
Ex- RRS HSE TDV6 07 Java Black, bi xenon, corner lights, side steps, tints, cool box, smoke side repeats, chrome "sport" boot sill
Ex - Audi A4 Cab 3.0TDi Quattro
Ex - Freelander2 SE TD4
Ex - CRV Auto

How much?

I had the Tire Pressure monitoring system on Renaut Laguna, nothing but false readings, trips to the stealer at £25 a time, in the end i just put normal valves in. 07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))

I'm waiting for reply on price. Of course I'll post the reply when I get it.

There are plenty of other systems out there...some good and some bad. Research will pay dividends in the end for a product that works well. I have the Tire Dog system on my Discovery and have not had a single problem with it...very happy and very accurate. $169 well spent.

In the past 6 months I've had two perished/split valve stems hence I want something on my Sport as well. Retrofitting the LR system will cost a fortune and is time consuming to install. Ra-Ro Sport Super Dooper Charged.

I opted not to get the TPMS on my RRS as the systems I had on my previous Audi's and BMW's we're shocking.
Can't see this as being anything better. I think TP systems are a great idea, but the execution doesn't seem to be quite there yet.  ON THE WAY: BMW F21 M140i
MERCEDES GL350 - Metallic Navy Blue w/Grey interior

GOING: BMW F31 335D MSport+ xDrive Touring
GONE: Land Rover Discovery 4 HSE - Stornaway Grey w/Black Interior (wish we'd kept it )
GONE: BMW F10 520D MSport - Carbon Black
GONE:MY12 RRS SDV6 HSE Sumatra/Ivory/Grand Black Privacy glass

My TPMS has only alerted me twice............and both times it was right......slow puncture.
