I am going to be returning my unit to Grom for a refund. Wifi and bluetooth connectivity doesn't work, there's minor video interference in all modes (OEM and Vline) and to top it off, the gps antenna wiring simply broke while carefully trying to remove the plug from the back of the unit. At 22 gauge or less, the wiring isn't going to hold up with any flexing over time.
I'll keep an eye on the unit to see if they get better over time, but as it stands I don't think this is ready for prime time. I'll be doing some reading to see which unit provides the best bluetooth audio A2DP connectivity as the Audiovox unit I have now is subpar.
Good to hear and thank you for the update....Looks like a no go for me then right now. Will just focus on a Bluetooth interface.
