I wanted to provide an update on this.
Without responding to my service requests to provide the proper wiring harness, I did receive an RMA approval by email in January. Despite the terrible support at least they were willing to take the radio back. I opted to keep the radio and have since installed an aftermarket amplifier. Using the adapter that was supplied with the radio for after market amps (bypassing the factory Bose system) I now have all 4 channels of sound. Actually 5 because the harness for this has a subwoofer line out as well.
I did ask if I could purchase an additional harness and as I expected I received no response.
My advice to potential buyers is to expect no support from the seller. Limited support from the community (there is just not a lot of these out there and you would need to find someone that has your exact radio, car model, year and options). If you do get one check everything before your return window closes.
Wow! As you said, I heard support would be bad but didn't expect it to be that bad! Their site says to send them a picture of your car if you want to verify compatibility. So, I took a picture and sent it to them. That action created a ticket in their system. It has been about 2 weeks with no response. Given that my ticket would be the kind of ticket to generate a sale, I thought my kind of ticket would get looked at. So, I thought maybe because of the holidays they might be slow at answering tickets. Your experience doesn't bode well...
Give them a call. It escalates the ticket in my experience if you speak with them in person.
Got my radio on 4/14 and i have had nothing but issues with contacting them. Their CSR (Angela) will ask for the system info (which i have sent several pics of) and close the ticket. I find that if you can reach Chris, he's pretty responsive, but i am still waiting for an update of my software that is supposed to fix the issues (7) which i am having. The concept is great, but the customer service and support is lacking tremendously.
The back and forth is pretty bad. Nice people, but the problem never got resolved on my unit for 4 months. I eventually requested that they exchange my unit for another model. I am still awaiting my exchanged unit but understandably is taking longer due to Covid19
My advice, if they are not able to resolve your issue I would go to their website and submit a service/return request from their contact-us form. They should either A. Finally work to resolve your issue or B. Exchange your unit.
You just want to make sure you are not stuck with a head unit that does not work correctly.
I've been asking for a couple of weeks what type of connector is used for the WiFi antenna because I need to extend it. There's been back and forth but no answer to my question. I just need to know if it's SMA, RP SMA or something else. I'm not sure why that's difficult for them to let me know.
