For augmentation bundles, you apparently can get the wireless turned off, at "about a grand per item", by a street doc. I am annoyed that they stuck this in the shadowtalk, instead of the rules where it belongs. The bundles overall don't impress me a lot. The miniscule Essence savings will usually be offset by being stuck with unwanted or too low-rated individual augmentations.
That's not a rule- the rules specifically state it's built into the hardware not the software and can't be undone.
Remember, not everything stated in shadowtalk is true.
However, the caveat as always, it's your home game and your GM can decide it any way he wants.
Personally, if I was GMing both augmentation bundles and cybersuites would follow the rules of cybersuites.
It's a value package that doesn't work with other cyberware.
Some of those bundles are good for starting characters...
Just save up a fortune nd when you are ready, rip it out and get your new ware.
