car repair shops hate this one sneaky trick

Seriously though I completely denied any additional warranties bc the car was expensive enough but I distinctly recall the dealership doing their best to scare me into an extended warranty, stating that they have $10,000 equipment that’s needed to diagnose and fix future maintenance issues.

My brother-in-law has a collision repair shop and is a gifted mechanic. I was hoping between the two of us we could use a device like this to diagnose and fix any issues.

Is this what would be needed?
Sorry, I just hate to make assumptions .

This looks super cool. What is it?
I Googled NMO but that was useless lol.
My best guess is some form of communication with the mothership?

NMO is a type of antenna mount for vehicles. It’s the most common by far for any type of two way radio use.

A 3/4” hole in the sheet metal is required.

yes if that is the item selected then that is what you will receive, even though it is a china website they are legit.
just note that the software on that one is for GM only

Did you drop the headliner to get access? How much of it? Greenlee punch or similar I’m assuming.

Nope the rear plastic panel that covers that last row seat belt that I removed pops off which gives you some access to rear of roof. A little bit of heat and a 2x4 to pry headline away from roof did it for me. And I did it by my self.

The only thing I had issue was was putting silicone around the second mount I am in California we are in a drought there is no rain so I don’t need to worry about water getting inside except for going to the car wash but at some point later I will make my own pipette another silicon because you can’t really pry the headliner down too much or you’ll break it I didn’t want to pull the side panels off to the rear seat belts and Unbolt bunch of stuff. Easy

I use 3/8 NMOs like this which gives you a smaller hole to drill “3/8” and more surface area to grab

How did you decide to mount them off center, instead of on the centerline?

Because the center line of the roof is not wide enough for weather sealing plus there’s “a tiny gap” which will cause corrosion. Therefore, you cannot technically mount a antenna in the center of the vehicle which would be optimal however for what I’m using this for I’m happy with what I’m getting as far as reflected power goes

With the mayor of Tahoe it has five fans one down the center to one side therefore you cannot technically mountain antenna in the center of the vehicle which would be optimal however for what I’m using this for I’m happy with what I’m getting as far as reflected power goes

I totally brain farted on this. Despite seeing it in my own pics, I was thinking about thecopcar and theothertwin. Each had multiple antennas on the centerline. Looking at this pic, it dawned on me the thethirdtwin has a rib in center, not a flat.


@Ohannon7 thats a bare NMO on the roof before I mounted the antenna.

 

[Ghost10]

Uh oh face to face!

Which one is mine ?

I have a moon roof so rear is my only option remember the glass has to open as wide as it is you double the length.
