As I mentioned above, some apps are blocked from AC/AA because they are deemed to be a distraction to the driver, which is why you can only see a selection. Waze being a map app, is of course, allowed, so if you don't already have it on your phone it should just be a matter of downloading it and away you go. One thing I noticed on mine is that some apps (like Amazon Music for instance) have to be set to Autostart or I just get a message saying "Amazon Music is unavailable at this moment". However, that could be because I'm an Android user or because mine is a third-party unit; might even be a combination of the two. You really need someone else who uses an Apple phone and the Lexus unit to advise you further.

I've got a 2018 RX450h Luxury and I didn't even know that it's got an RPM gauge! I have no idea what it could be but I will say that I never use Eco mode so try it in 'normal' mode and see if it still happens.

Strange. I had a Mk.1 and two Mk.2s and they were brilliant cars. When I couldn't get another because it became the Scorpio, I moved over to the Rover 800 series; first an 827SLi and then an 800 Sterling.

I was a big fan of the Granada back in the day. The picture below is not my actual car but I did have one of these, the Sapphire Edition. It was the last one I had because the Scorpio took over, looking like a big jelly mould.

It doesn't matter how technically or mechanically good they are, if a car is piggin' ugly no one's going to buy it, at least not in enough numbers to make it a success.

OK, perhaps I was a bit harsh so I apologise for that. I suppose it's partly down to the fact that we have all taken the driving test and so we should be able to drive, but perhaps it's more down to the fact that I've always loved driving and never been the slightest bit nervous about it. I had my first lesson on my 17th birthday and passed first time not long after, back in 1975. I still get as much pleasure out of it now as I did then. Something else that I suppose played a part in my experience was working for BT and driving a few different vehicles. I was a cable jointer and on my first day I was asked if I could drive and when I said yes, I was immediately given the keys to one of these jointer's wagons. I'd never driven anything bigger than a Morris Marina before that day! No messing about, just get on and do it, so I did. Within a couple of days it was a doddle.

I spent many years as a telephone engineer with BT so driving my van made me very comfortable at reversing with the door mirrors alone. So much so that even to this day, 20 years since I was last in my BT van, I still reverse that way. The only time I ever glance at the camera screen is when reversing up to a wall or something similar, otherwise my RX450h can be seen reversing at quite a rate of knots down single track country lanes or wherever it needs to, by the door mirrors alone. No offence meant but I have no truck with folks who say the RX is too big or whatever. We've all passed the same driving test. My own sister in law takes the proverbial biscuit though. She just cannot parallel park and will genuinely just abandon her car and ask a complete stranger to park it for her! I would confiscate her licence if it was up to me but, thankfully for her, it isn't.

Yes indeed John, both as ugly as an ugly thing on World Ugly Day

The Renault Vel Satis and the rest of its family fell from the top of the Ugly Tree and hit every branch on the way down. Hideous things.

I don't think they'll update the Lexus maps and install AA/AC all for £80, not when map updates cost more than that on their own. But it doesn't matter that the Lexus maps are out of date because you'll be able to use whatever maps are on your phone, such as Apple Maps, Google Maps, Waze, Sygic or whatever. Apple Carplay/Android Auto are basically just an interface between your phone and the car, so that you can almost* mirror your phone screen to the bigger in-car screen. If you were just going to carry on using the Lexus mapping then it's hardly worth it. *Almost, because some apps are purposely disabled for use while the car is in motion.

Or, if the OP has somewhere like this near to him

Someone took out the tyre insurance and had to claim on it within about two weeks, due to getting a nail so close to the side wall that it was irreparable, so he almost got him moneysworth straight away. GAP insurance was quoted as £399 for 3 years cover at the dealers but I got the same cover for £175 from https://www.motoreasy.com/ and similar for paint protection.

Try again in an hour or so, may just be a transitory thing. Seems to be a server-side error.

Brilliant, thanks Colin

Parking sensors were a dealer-fit option, not factory fit, or so I believe anyway.

I know the fuse box I need is probably in the passenger footwell but I have an inner-ear problem that means if I put my head in a position to see it, I'll get vertigo and be violently sick. None of my internal lights are working so I'm assuming a fuse, probably the 'DOME' one, but can anyone confirm that that is correct and the location too? Googling brings up thousands of 3RX fuse box images but none for 4RX that I can see. When I have seen the year 2018 mentioned and I get all excited, it usually turns out to be for a Ford or some other completely random car - anything but what I'm looking for.

Second post down from the top, just click on that picture headed 'Android Auto or Apple Carplay - Carlinkit Decoder 2.0' for the details.

I'm afraid that there's no such thing as a Carplay module. If your car is recent enough, a Lexus dealer will do a software update for £80 to give access to Apple Carplay/Android Auto. If it can't be updated then there are external units that can be bought for about £200 to £600 that can be integrated into your car multimedia system, but these are third-party devices and not available from Lexus dealers.

No, that's the 'aux' battery that starts the hybrid system and runs the 12V systems. In a hybrid the 'main' battery is the high voltage traction battery. That seems strange but there you go. Have you not got a laptop and Techstream yourself? I'd still get the 12V battery properly load tested first because that's obviously the cheapest option. If that's alright and the wiring harness and associated connectors are alright and it looks like time to replace expensive items, I think I'd be tempted to look on eBay/breakers for a cheaper, secondhand solution.

I think the Apple Carplay could be used wireless if you so wish. I do know that Android Auto doesn't have that facility yet but I also wonder just how useful it is because the phone will need to be kept charged up so you may as well have it plugged in anyway.

With that many lights up the first thing I'd do would be to have the 12V battery tested. When they start to go they can produce all kinds of weird and wonderful light displays.

Basically it allows you to almost* mirror your phone screen on the big car screen. *Almost, because there are only certain apps that will work in Apple Carplay/Android Auto to avoid breaking the law. For instance, it's illegal for a driver to see any sort of screen other than a satnav screen whilst the car is in motion, so you wouldn't be able to play YouTube videos or stream Netflix movies while the car is moving. Primarily, it's greatest use is in navigation. Factory-fitted navs tend to be inferior and don't get updated much. Using AC/AA means that you can use Google Maps, Apple Maps, Waze, Sygic or whatever your favourite mapping and navigation system is. These are all updated regularly and traffic info like accidents and traffic jams are almost updated minute by minute.

Goodyear Vector 4Seasons Gen 2 are the best tyres I've ever had. Quiet, superb in all weathers, really makes the car feel very sure-footed.

I think it's the other way round. This person seems to have a fault with the media system because it powers up and he can adjust some parameters but not others. It's the OP 'River' who seems to want to reject the whole car based on the (working) multimedia system.
