There is no navigation. Just the sport standard screen. It's just the dealer says that there is not upgrade but his is very weird since the date of the car is 2014 with no upgrades in the meantime.

Which is the latest firmware for is300h?

Guys I owe a 2014 Lexus is300h f sport with no navigation and I want to update the firmware to the latest version. Where can I get this? I will really appreciate your help on this.

Guys thanks for your answers but I think you have misunderstood me. What I am saying here is that my whole climate control is off, fans off, ac is off, s-flow is on. Air is still coming in through the vents even if the circulation of the air is in the "inside mode". Is this normal? I thought with this setup no air will be coming through the vents.

Hi there. I am new to the forum and I have a question about the climate control of my IS300h. Even if the AC is off and the air is disabled in coming from outside, air is coming through the vents related to my current speed. In addition, when I have the driver windows opened more air is coming through the vents. When I switch to air circulation from outside more air is coming through the vents. Is this how the AC supposed to work?

Hi guys. I owe a LG Nexus 4 phone with firmware 4.4.4. Everything related with calls work just fine and I have a problem with the SMS and the emails. I cannot see any sms or emails and i can not even synchronise. The site of Lexus indicates that the sms and the email of this phone with firmware 4.4 work just fine with my is300h(no navigation) Is there an incompatibility of 4.4.4 with the is300h system or there is something else? Second question, is there a way to display the current fuel consumption under the revmeter as a number and not as a moving bar with a triangle indicating the best consumption?
