AR Perception, questions questions Options

[Skippy]

Hey all,

I'm gradually getting up to speed on sr4 'wireless world' rules, but there are some lingering things I'm trying to work out so that I can finish my character for my game this weekend.

AR perception. P. 209 says that this can be achieved via things like image links, soundlinks, touchlinks, AR gloves, glasses, headset, etc... connected to your commlink. However, after a few paragraphs of detailing these ways that people access AR, it states that the easiest and most common way to get your "AR fix" is to use Simsense.

Now, an internal commlink comes with a sim module built in. I'm assuming that this is all I would really need to access AR then, right? If I DIDN'T have an internal commlink, I'd need either my external commlink + an external sim module + trodes or a datajack or something OR my external commlink + an internal sim module (DNId to my nervous system...) right?

I was looking through the sample characters (which aren't usually all that helpful, unfortunately) but I noticed that many of them have no audio gear but have sim modules... is this the way that they are like, receiving phone calls, hearing audio signals that they have messages, etc? Or are they not able to hear those things?

Honestly, my character has the Sensitive System flaw and I'm trying to minimize the amount of Cyberware that he'd have crammed into his system. I don't want to take things that are just redundant.

Thanks!
