Thought I'd add for anyone looking to get one that current pricing is based on 3 specific features:

1. GPS with dedicated SD card slot for storing maps
2. Android screen-mirroring
3. Steering Wheel Control

For me the point of these units is primarily to get my phone Bluetoothed to the car and off the windshield.

There's absolutely no point imo, having a 7" screen if you still have your phone obscuring an already pretty limited field of view.
So to make it worthwhile you need your navigation there too.

Some units don't have built-in GPS but do have screen-mirroring.

This casts your phone display to the unit, allowing you to view your google maps navigation or whatever you use on the DD's screen.

This is great for music players as well, as your familiar library structure is preserved.
Speaking of music, some of the units only support MP3, WMA and WAV, so if you have your library ripped to a lossless compressed format like FLAC or APE, then you need to double check those are supported.
Only the very cheapest seem to have this limitation though.

I'm a bit confused about something. I can't see any reason why the SWC wouldn't still function when using screen-mirroring, but maybe I'm being a bit optimistic.
Does the control signal get bounced to the phone over BT?
So if you hit next track on the steering column, will the instruction pass through to advance your phone's music player?

Anyway, the current best model that supports all of these features is the 7021G, and the cheapest I've seen it sold for new (only checked eBay) is £55.94 from China:

You can get a unit that supports SWC but without GPS or screen mirroring for £39.99 (the one below doesn't state SWC in the ad but I asked them and they confirmed this one does):

and this one for 35.99 that supports screen-mirroring but no GPS or SWC:

These might be cheaper on alibaba etc, I haven't dug around there yet.

Hope this helps narrow it down for someone.
