I am looking for some help please.
We have a 2012, 76 series Landcruiser that came with a no name brand double din radio fitted. We use it for both the radio/music as well as GPS mapping. The radio & GPS functions work fine but the screen on the unit is near impossible to see when driving towards the sun due to reflected glare. We have tried every thing available but have not ben able to combat the glare as the dash / radio screen angle cant be altered. In our old 100 series TLC we had a radio with a screen that tilted to insert CD's and you could adjust it to reduce/stop the glare but those radios no longer exist. We also use a Codan HF radio for communications when out of phone range and use a Sony MP3 player to stream music via Bluetooth when out of radio range or there is nothing of interest on the radio.
We tried a unit which was very nice but it still had bad reflected glare and it also generated lots of interference on the HF radio to the extent that the HF radio became unusable with the radio switched on. The HF radio tech advised that the issue was the double din radio which is basically an Android tablet computer that is not shielded and it emits RF that interferes with the HF radio.
We've been reading on this ExploreOz site about the CarPlay/Android Auto adaptors that can be used with ordinary radios (eg factory, Sony, Pioneer etc) that emulates the Android OS and you can download Android programs onto it and run them on the ordinary radio. I have contacted both the companies listed but have not been able to get a reply regarding the units and what RF suppression they have - are they C-Tick certified? Trying to find one local to see/try has not been successful and I'm not keen to spend lots of $ only to find it doesn’t work. While some places accept returns it must be unused and they want a 25% restocking fee.

We would love to hear from anyone who can give some feedback on the following:
1/ What brand radio unit have you fitted in your 76 series TLC that does not suffer from reflected glare to the extent that you cant see the GPS mapping on the screen?

2/ for those with HF radio in their vehicle, what radio unit do you have that does not generate interference on HF radio - in particular the VKS, BushTelegraph & Austravel frequencies?

3/ for those using the CarPlay/Android Auto adaptor -
a/ Can you stream music via Bluetooth to it via a MP3? (one android OS unit using Android 10 we tried could not receive BT from a MP3 player at all, it only accepted BT via an iPhone or Android phone. I should note that the MP3 player happily streams music to every other BT device I have tried in the past)

b/ Can you play music from the radio or streamed music via BT at the same time as the GPS/Mapping is being used? (again, an Android OS unit we tried could not do both at once. Driving with a choice of only one of GPS/Mapping or music is not an option)

Sorry, lots of questions and thanks in advance for any feedback on these items.

Give ecoffroad/ecvisionsound a call.

They sell and install a lot of android headunits so may be able to answer your hf compatibility question.

There are android head units that can display exploroz and any other app and play music as well. I have a 9" in my 22 79. It works well. Not as fast as a good phone but does the job. Glare is in part possibly due to the 79 shape etc. I dont have a major issue, but often have a canopy on when using exploroz.

I have similar issues with my flat 7 inch non adjustable screen in my prado 120 digioptions I ended up using black thick craft paper as a shield around screen to see the map

Only problem is I can't read screen very easily so I now use a tablet using polarised sunglasses during daytime blanks screen just as bad if not worse on the 7 inch

Tony,
Your HF radio interference problems are not new, it is a can of worms that has been open for a very long time.
It isn't as simple as just the frequencies you operate on. There is a lot happening inside your radio that isn't directly related to your target frequency, they have usually one sometimes two intermediate frequencies that is mixed....blah blah blah.
Your head unit may be interfering with these frequencies but different brand HF radios use different IFs so what interferes with a Codan may not worry a Barret (example only). It is a very complex field and needs some specialised equipment to identify the emissions frequencies and if they are in the range of the IFs in your HF radio most likley not economic to rectify.
That's assuming the interference is comming in via the antenna or coax and not the supply line.

I would suggest asking the same question in a group that focuses on your particular brand of HF radio.

thanks for your reply and information. Having worked with a very experienced Radio Tech' and Redarc to identify and isolate an issue in the past I am well aware about the possible causes and how complex the issue can be to identify and rectify, it possibly has me more alert to the issue than others might be in the same situation. To that end as I am keen to use the ExploreOz mapping product and need to upgrade our radio head or use an AI adapter as recommended here, I am asking here if anyone has had any first hand experience with this so that I can make an informed decision about which way to do the upgrade. Cheers.

Just as a matter of interest what was the issue you wrre trying to resolve when you were working with the radio tech and Redarc, and how was it resolved if at all?
