Yes and no ....
I just pulled the trigger on upgrading my Rubicon Unlimited to a new X109 (and purchased the module with it to control accessories, but haven't had that installed yet). I got the whole package, including the Sirius/XM satellite radio module and installation of everything but the accessory module for just under $3,400 (tax included).
Yes, this is a LOT of $'s for a head-unit, and by far the most I ever spent on one. But there's a lot to consider about this one. The fact that it includes a whole new center console panel, so it looks like an original factory installation, is a big benefit. To get an install that looks this "clean" with any other stereo, you'd be stuck paying a shop quite a bit of money in labor to fabricate something custom for you.
This whole trend of doing everything in your vehicle with your smartphone kind of stinks, IMO. It's really just a cheap hack at the end of the day. My phone gets used plenty enough as it is, without it having to serve double-duty as the core of my vehicle's sound system every time I drive someplace. I haven't seen any of these navigation stereos that actually CHARGE the phone or tablet while it's attached to their USB port either. (Why they don't is a good question ... but they just don't tend to design them to provide enough power on the port for that.) So on a long trip, I eventually have to disconnect my phone from my stereo anyway or else the battery runs down.
I like the idea of my stereo supporting the OPTION to stream Bluetooth audio from various applications and it certainly needs to allow hands-free calling. But I expect my car's head unit to be totally "self sufficient" otherwise.
And so far, the cheaper navigation systems I've seen for cars have some trade-offs. You usually get a smaller screen (or one that's not even anti-glare in a few cases). And GPS functionality varies, too. One thing I'll say about this X109-WRA is the GPS is really full featured. When I crossed a state line, it immediately popped up a box asking if I wanted any additional info for the new state I was in. If I tapped "Yes', I got a summary of the state's speed limit laws for different types of roads. When I took a detour off the highway while it was routing me home, instead of going crazy announcing "Off route! Recalculating!" -- it prompted, asking me to confirm if I was taking a detour for gasoline or food. If I picked one of those options, it offered the closest ones it knew about off that exit. And after going to one, it picked right back up with my original route.
Oh, and even the SiriusXM support beats what I had in my factory 730n radio. I get an additional 20 or so channels that only newer receivers can pick up. So more for my subscription dollar on that end too.
So is this whole thing worth the $3000+ price tag? Well, you and I both know it doesn't cost NEARLY as much to build this stuff as what they sell it for. But you're paying to help offset all the R&D money they invested in bringing the design to market too. If nobody is willing to pay for something custom and this nice, then we'll never get anything custom and this nice. I hope I can get back at least a little bit of what I spent by reselling my 730n on eBay, and reselling the separate EQ/sound processor I used to have in my Jeep to try to make the 730n's poor sound quality more bearable.
The days of a $3000 headunit are LONG LONG LONG gone. Manufacturers are losing their shirts thanks to ipads and iphones that can control the space shuttle, let alone some lights. OEM navigation used to be thousands of dollars (it still is for some models, but that's going away)...now you can get navigation for $400-$800 in OEM vehicles, and even that will start dropping and become standard equipment. They will sell 4 units to starwood and the rest will rot on shelves until they get sold for the $1100-1500 that they are actually worth.
