  1. Ok thanks. Does it have an inbuilt function to find an unused frequency, or do you have to manually search for one yourself?
  2. That's just what I was thinking. Which brings me back to my original question:how difficult is it to find a spare frequency?
  3. Thanks Richard. Is it difficult to find an unused radio frequency for the transmitter to use? What happens if your journey takes you in to an area where a new radio station is detected on the frequency you are already using for your transmitter?
  4. I know that we have a few threads with recommendations for adding Bluetooth connection to a rx400h, but I don't recall seeing a report about one of these:https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F254239691426 Has anybody used such a device to stream music?
  5. I've been wondering about this since I got my rx400h. Is there some kind of service mode which forces the engine to stay running, and also respond properly to the throttle control?
  6. Welding the nuts won't make any difference as the thieves cut through the exhaust pipe. Although this is noisy, it is also very fast and they're gone before anyone notices.
  7. I've been wondering this myself. It is worth noting that there are many posts along these lines with various recommendations about non-Lexus solutions. For this reason, I doubt that there is a simple plug and play upgrade from Lexus, though I'd love to be proven wrong. My rx400h is a bit older than yours, so I believe that yours has different controls and displays, but with the same underlying functionality.
  8. Which wire in the roof lining of your 400x did you need to connect to? Was the connection to the battery to provide 12v supply to the caravan for charging leisure battery, etc?
  9. I have just invented a new service schedule for coolant change. The easy method: Instead of changing ALL of the coolant every 5 years, drain the radiator and change ONE THIRD of the coolant every 18 months. (I expect somebody will be along in a minute to tell me about a problem with this method....)
  10. It all looks so easy on the workshop manual: two nice little plugs protruding from the front side of the block. What they don't tell you is what else needs to be removed in order to see these taps / plugs. I can't see anything remotely like those shown in the diagram. What I have spotted is a round metal cover close to the oil filter - slightly higher and to one side - held on with two nuts. What is behind this cover - it does not look in the right place to be related to these drain plugs.
  11. OK Herbie. I've now determined that 3.6l drained, and I'm now in the process of refilling with the old coolant to ensure that it really was full (to save wastage of new coolant). Initially, I couldn't find the relevant section in the workshop manual, but I now have, so no need for you to look it up. There are two drains on the block, apparently.
  12. I noticed that the service schedule for coolant change is 10 years initially, then every 5 years. I was wondering why new coolant does not last as long as that put in when the car is new. Perhaps this is because at coolant change, the change does not actually change all of the coolant - and some (half?) of the old coolant remains?
  13. My drive has a slight gradient and the front of the car is down hill. Is that in any way stopping the system from emptying of coolant? Wondering if I should momentarily start the engine to get it circulating and help it to completely drain?
