The internal automatic antenna tuner can be added to any Omni-VII that does not have the autotuner already installed as a user-installable kit. The kit includes a completed circuit board, all necessary cables, and illustrated instructions. The AT588K is a no soldering required installation

Great product (as always from Ten Tec) but one suggestion:
In step 12: The cable marked #19 is preformed in such a way that it wants to be installed into J1 upside down; The picture doesn't show the #19 so one can assume the label needs to be installed so the label is towards the top of the radio....just was a little confusing.

After finding out that this was the new, improved board (layout and numbering was not consistent with directions), the install was almost trivial - only issue I had was getting the top cover back where it belonged (the fit was quite tight). Now that it's installed, it has made operating MUCH easier.

I purchased my Omni VI in June of 2012. I did not get the internal tuner. I decided to add the tuner, and found that the instructions were well written with color photos making it easy to install. The radio covers need to be removed, and a shield removed in remounted with the tuner. 2 mini coax connections and 1 6 pin cable are the conections to the radio. It tunes quickly and quietly,easy operation. It works well on all bands and is a good addition to a great radio
