"Good ones" is highly subjective and every brand has it's fans and detractors, though most people on here tend to gravitate towards the Big 3 manufacturers...i.e Alpine, Kenwood, and Pioneer.
Your stated requirements are pretty low....just about every NAV unit currently on the market is going to support the rest of your features to one degree or another so a list of recommended units would literally look like a grocery list. You'll need to help whittle down that list in order to receive useful replies.
Some other things to possibly consider are:
Budget?
Required screen size? 6"? 7"?
Why the aux input? i.e. what sources are you trying to hook up?
Will you use a cell phone with it? Android? iPhone? iPod?
Stock or aftermarket speakers? Are you using an amp? Subs?
Will you use a backup camera?
Do you need or want voice control?
These questions are by no means comprehensive but should serve to get you started on some reasonable recommendations.
