Default 360 MAX GPS Connection Issues

I have been using my Max360 since Christmas and have had zero issues up until the past couple weeks. when those couple of weeks, I recently just bought a 2018 Silverado and the GPS is having issues connecting to the satellites.

On my previous 2014 Silverado, my max360 was mounted to a rear view mirror mount and had zero issue connecting to GPS. On this truck, my front windshield was tinted and had a visor strip, again, zero issues with GPS connection.

Three weeks ago I got a new 2018 Silverado and had the windows tinted exactly the same as my previous truck from the same installer. The max360 is mounted in the same location under the rear view mirror using the same mount and over the past two weeks, I have had a lot of trouble connecting to GPS.

I was going to upgrade the firmware last night but I didn't have the right cable but Im not sure this will solve the problem, based on what's in the update. There are times when the radar will pick up GPS signal but then lose it. I tried different locations on the windshield and the results varying, if anything, the rear view mirror mount for my current truck is more open than my previous truck as my current doesn't have have the GM sensors.

I contacted customer support yesterday and they think it has to do with the tint but up until the past couple weeks I have never had an issue. I put my old 9500 in the truck yesterday on the same rear view mirror mount and it had no issues connecting to GPS. With the max 360, I'm still picking up police radar when they pass so I don't think its the tint especially since it worked fine on my last truck.

Does the 360 max have to be connected to GPS in order to properly detect radar? Has anyone had this issue and possibly found a solution?

Any help would be great, I would like to use my mirror mount as it get the radar off the windshield and I have it hardwired in. I would have expected the max 360 to have a better/stronger GPS signal than the 9500, but that doesn't seem to be the case.

Thanks,
Dave

Try this -

Park your truck in your driveway or on the street. Hold your detector outside of the truck and power it on. The detector should acquire GPS within two minutes or so. If it does, then I suspect that the installed tinting isn't the same as the tinting that was in your previous truck, and that it has some metallic content in it that is preventing GPS signal acquisition.

If the detector doesn't acquire a GPS signal while holding outside the window, then it might an issue with the detector itself.

Whether or not GPS is connected, this doesn't impact detection (although metallic tinting will reduce your detector's sensitivity). I use a Blendmount myself with a hard-wired setup, and I have no issues connecting with GPS.

Thanks for the reply. I will try that but is there any difference in the strength of the 9500 and max 360 GPS connections?

The reason I ask this is because last night I had zero issue with the 9500 being connected to GPS. I would have thought the 360 would have better GPS capabilities since its newer and a better unit.

I did contact the tinter this morning and they assured me they aren't using the tints with the carbon in them so there shouldn't be an issue. The tinter said the have been using the same material for years.

The Escort service reps said that the radar being under the roof of the truck would impact GPS.

Per TBNTX's comments, it's metallic additives that can be a problem, as opposed to carbon.

I don't know the answer to this question. I'll do some comparative testing between my Max 360 and my 9500ix, but my tests shouldn't be considered "conclusive" in any way. Only EscortRadar could offer any official answers.

Not "carbon" content. Metallic content would be the culprit, if present in the tinting film.

Yes, that would be true. If the position of the detector is further back in the cab, and the GPS chip is blocked by the roof of the cab, then the detector won't get a good lock from the GPS satellites.

Thanks for looking into this for me.

Like yours, my detector is mirror mounted under the metal rearview mirror and worked fine in this truck and my previous. Im at a loss, because I don't think its the tint based on previous experience with the current truck and previous truck.

I would have thought the GPS signal would be very strong on these units based on the features and have the ability to get reception similar to a cell phone. My cell phone GPS works perfect. I know that's not an apples to apples comparison but I don't see how the GPS signal is so weak.

We recommend that the top of the detector has a clear, unobstructed view of the sky. Does your rear view mirror (RVM) assembly obstruct it? If so then that is the culprit. Some modern vehicles have huge RVM assemblies which will obstruct the GPS signal on devices mounted directly underneath them.

We use SiRFstar GPS chipsets in our detectors. These are very capable GPS receivers.
