I'm sure everyone is annoyed with this topic by now, but i had a few questions i haven't seen answers to.

Head unit Options
Subwoofer Options

My main goal is to have improved sound. I'll admit it would be nice to have a nav screen that doesn't look like its so old.
The options that seem appealing to me are the Vline V2 or converting to non-nav climate control and adding a stereo.
Regardless I will replace the main speakers in the truck.
What is the general consensus on the Vline? Is it slow to start up? Is the sound quality really improved?

I have seen the SCAR subwoofer upgrade. I don't want a big box in the back, but I would like better bass, so this seems like a great option
I haven't seen anyone do a highline out and add a mono amp so you can run a traditional 4ohm subwoofer. Is there a reason no one seems to be doing this?

Are there newer or better solutions I havent read about
 
Nothing?

The more i read the more the Vline seems buggy and not ideal.

How much is the factory radio holding back the sound quality?
Should I just do the GTA for bluetooth and upgrade the speakers?
Or is adding an aftermarket headunit with the facotry ML amp really going to improve sound that much?
 
I have an 05 and an 06 GX470. I have a Grom VLine 2 in the 05 and it works as well as any mid-tier head unit replacement. The 06 has a more crisp display being a year newer and 50K less miles, but It could also be electronics improvements between their manufacture. It is never going to feel like a new Carplay-enabled system because of that older display.

Forums suggest the Phoenix head unit replacement may work well if you buy the custom firmware. These reviews trend overly optimistic - everyone shows off the finished product but doesn't come back and update the review nine months later when systems fail. I have a Kenwood in another vehicle and technically you can say the same of that. Kenwood abandoned it after a year with no firmware updates. I physically inspected the Phoenix and it is no worse than any mid-tier head unit. I would not waste time trying to do the dash-control conversion, you will never find the parts.

I put a bluetooth-FM transmitter in the 06 and you are not going to be content with its audio quality. I don't see anyone actually doing it but audiophiles could build a standalone system using a soundbar or similar setup and abandon the in-car audio entirely. The ML mess is too much to unwind, which is a shame because otheriwse simplfiy the electronics (and reengineer it with a timing chain instead of a belt) and the GX would be perfect.
 
I'm leaning towards the Vais bluetooth adapter and upgrading a few speakers.
The FM transmitter is a hard no. Even in the 00s i wasn't ok with those.
 
There is the Teyes head unit that can replace the factory navigation equipped system. I plan on going this route with my GX470 and install the 360 degree camera option as well.


My friend has it in his FJ and he's had no issues over the past year thus far.

This review (and some others) scared me off from this option
