If I have skill wires 4, go wireless and load in gunnery, piloting ground craft and piloting walker my piloting aircraft heavy weapons throwing weapons arent being used unless I swap them out much like my neocortial is only being in use until I swap it out for limbic or control rig booster nanosystem or o cell or oxyrush one system can only be active at a time for nanos
Whoa, Your understanding of how nanites works are very different from mine (and some of the others too I presume), not saying that you are necessarily wrong though.

Am I to understand correctly if your version goes like this:
character buys hard nanohive rating 2 for 24,000 nuyen.
Character then buys Anti-rad rating 2 for 12,000 nuyen.
And Control rig boosters rating 3 for 18,000
and finally markers rating 1 for 2,000.
Now the character can choose to have 1 of those active at a time (or maybe 2, because the hive is rating 2?) and at any point he can choose to "reprogram" them into some of the others he already bought. e.g. Character has anti-rad active (cause he lives in glow city) and later on, gets some juicy CEO scandal pron and decides to carry those with his markers system. He therefore reprograms his anti-rad nanites to be able to carry the files instead. Is that how you see it working Rooks?
because I see it as this:
Character buys a hard nanohave rating 2 for 24,000 nuyen
and implant medic rating 6 for his datajack for 600 nuyen.
Aaaand andother rating 6 implant medic for his second datajack for 600 too.
Now the character can have both active at the same time, because his rating 2 hard nanohive can handle 2 colonies active simultaneously. The trick is though that hard nanites can be reprogrammed and he therefore can reprogram one of those to a control rig booster and trauma control system. (thus saving himself many many thousand of nuyen). This doesnt take any skill checks and happens automatically when the new options are selected. (and while I believe thats RAW, its not RAI, or makes any sense whatsoever)
I do believe though that your statement about neocortial, o-cell, oxyrush and limbic is incorrect. those are soft nanites and therefore cant be reprogrammed. They are either active or inactive. And requires a soft nanohive rating 4 at least (since you have 4 different soft nanite systems). (page 151. each nanohive supports one nanoware system at a rating equal to its own.)
*edit wait does "each nanohive supports one nanoware system at a rating equal to its own" mean that a rating 3 nanohive can support up to three different systems at the same time, at any rating. Or does it mean a nanohive rating 3 can support ONE system at up to rating 3?
Because if its the second one, then a nanohive cant even maintain rating 7-9 at all

and it seems to be crazy expensive then.
