Well, I don't have the Anniversary Edition, but in the basic book, they're right next to the info on Sensors, a few pages after the prices for commlinks. You could get yourself some glasses or goggles, add in Image Link and maybe a few vision enhancements, and you'd be good to go.
And Ben, you can actually go Hot Sim with just trodes. No need to get a datajack at all.
Edit: Reiji, datajacks can also be used for accessing chips and certain 'softs. Like, if you don't know Japanese, but needed to speak it, you could get a good rating Linguasoft to help you out.
