At least add which VL2 you are using and what vehicle it is plugged into. This is the problem with all these threads. The complaints are typically as much user error as anything else, and useless without enough info to actually apply to anyone else's use case.
1. I can say that my wireless Carplay with my iPhone works perfectly 90% of the time. I get in the car and within 20 seconds of startup Carplay is running on my OEM system with no intervention by me. There are settings on the phone and Grom that must be configured properly.
2. Have you adjusted the audio interface on your OEM system? On the LEX6 in a 2010-11 LX570, you have to adjust the audio settings for the USB interface. This improves sound quality greatly. For most VLine units there really isn't much reason to have poor audio unless something is broken or misconfigured. In the scenario listed here it's a digital connection between the VLINE2 and the OEM stereo.
3. Is this in Carplay/AA mode, or the built in app. Either way, it's most likely not the VLINE2's fault. It's most likely an app issue. I use Amazon music with no issues through Carplay.
4. I've only had to unplug mine one time in over a year that i've had mine.
5. I don't use the USB port, so can't speak to this.
6. For my unit there is a firmware that works better than others to mitigate this. (I would still consider this a VLINE2 issue, in case it sounds like i'm being a complete apologist)
7. I can't really remember having this issue, but considering the hardware and OS of a Vline2, it's entirely possible.
8. this sounds like the same complaint as above
9. Massive numbers of variables here again. Now you are adding different Vlines, different phones, and different Wifi connections into the equation. I can say, i've never had issue flipping my Iphone hotspot from Carplay to the native Android OS wifi connection when i want Android to have access to wifi. Possibly there is some confustion on your part about what the device is capable of. If you are connected to wireless carplay/AA, you can not simultaneiously have the GROM Vline2 on wifi (for internet access for native apps)
10. I don't use AA so can't speak to it's function.
11. I have found my iPhone to typically be the problem in these scenarios. When I get disconnected, I have found that if I start killing background apps on my phone, it will usually reconnect once enough are shut down. Insome cases, the phone just won't connect, and in other cases the phone will disconnect after 3-4 hours of playing fine. In either case, stopping apps on my phone resolves the issue.
I'm not trying to pick on you here or anything, just pointing out that at least some versions of the hardware running in some versions of 200 series work pretty well. Also, it's a fairly technical piece of kit, so some care has to be taken into setting it up properly to get the functionality you want out of it.
My biggest gripe is trying to get my phone to only connect to the OEM bluetooth for calling. I suspect this is more a Carplay/iPhone issue, but Carplay always wants control of the call. Even after I force the call over to the OEM connection, sometimes CarPlay will grab it back and move it over the Vline2. The Vline2 mic interface is far inferior to the OEM bluetooth calling, so this is frustrating when it happens.
