Yes, it's been over 20 days since I purchased the C3 and now I can comment at last. I wanted to power the C3 on my motorcycle via the on board USB port but I did not realize that the C3 Pro is not supplied with a USB cable. I then placed an order for a USB cable which has now finally arrived.
What attracted me to the unit initially was the price which is really inexpensive. Installing and setting up the unit is straightforward and no wonder the many YouTube reviewers sing the praises of this Carplay brand. In short, it's excellent, inexpensive and provides clear navigation on a motorcycle while your phone is safely tucked away in a pocket. Superb!

I am very pleased with my purchase.
The only backdraw is that I wanted to use it with my old rugged samsung galaxy x-cover 4 but that did not work since it has Android 9 as an operating system.
However with my new phone it works immaculate together with android auto and Where we Go.
I now purchased an optional usb cable for power supply.
Until now I used the under bottom plate hidden usb C port.

For the money, this device gives the most value out there what I have found. Check out my video on youtube for the install and review!

The product and the quality of touch screen and touch response is very good. Works Flawlessly. But the tpms does not work. Or I have no idea how to pair it. Can u please share a detailed video or guide?

As a starter to the connected bike world, the C3 is hard to beat, especially at the discounted price. It appears to deliver the full iOS/Android experience.

I recommend it.

Still, there are caveats, Some of these may be down to the iOS/Android functionality but without another device I cannot make that call.

The eye opener (for me) was that the available apps are severely limited by whether the developer has added integration. As an example, Calimoto does not work. Check first.

The iOS interface is much, much better. It's cleaner and adds many more apps.

Spotify was mercilessly pushed from my Android phone, such that I deleted the app. Is this the Aoocci profile, or Android Auto? I simply don't want media apps, please allow them to be blocked.

The connectivity is fine when if works but my OnePlus 8 pro really struggled at the outset, so much so that I thought I would be returning the C3. I have twice resorted to power cycling both phone and C3. things appear to have improved although I have made no changes.

The lack of an on/off switch, plus the captive power lead, is a real pain... It's an economy too far. There is a plug in the lead but the C3 side of the lead is too long and I doubt the quality of the plug will allow many disconnects.

I bought the C3 pro. This has the 3 point mount, and was significantly cheaper. If this is a long term buy (not a test of the technology) then go for the plus. That said the literature is very obscure as to what you are getting with the Plus and the Pro mixed up on the same page - with the non-existent Basic?

I expected a sunshade and a USB connector. This is probably down to the poor presentation on the website, it really needs improving.

The Pro has great (metal) mounting hardware if you want a permanent mount to a bar clamp. With the captive power lead I don't see that anything other than a permanent mount is an option. Fortunately at the low price (and with the excellent mount) this is a reasonable risk.

It's a very light unit, you can feel it's built to a price point, but the screen is great, even on the (slightly dimmer) C3 pro.

I have not tested the TPM yet, but that is a great bonus.

Delivery and the supporting tracking was fantastic. It was fun to watch the journey. The external packaging was also good, but the C3 and accessories were rattling around inside the box. There's real scope to improve the internal packaging!

My last point needs more investigation, but Android Auto appears to put the phone into a local hotspot mode to establish an ad-hoc connection to the display.

This is absolutely not a C3 issue, but it's another aspect of the auto connectivity game that I have not seen mentioned. If so then it will increase battery drain on the phone and needs to be considered for long long rides.

Given a second chance I would have bought the C3 Plus but, notwithstanding the comments here, I can totally recommend the C3 (pro or plus) as a great introduction and possibly long term keeper to connected bikes.
