Maestro RR preventing remote start

Hi, I have a 2018 4 Runner Limited (push to start). I installed a Kenwood DMX905S using the Maestro RR and later (a few weeks) added a remote start. The remote start is a Directed DB3 configured for RSR. The issue is that the Maestro seems to be interrupting the remote starter.

If I unplug the Maestro the remote start works with no issue. Starts and runs for the full 20 min run time.
If the Maestro is plugged in the remote start will start normally but only run for about 15-20 seconds.
The plug that seems to effect this is the 18pin plug on the Maestro. I disconnected all then plugged them in (starting with the 3 pin power plug) one by one, starting between plugs and waiting at least 1 full minute until one plug caused the issue. It happened to be the last plug which was the 18 pin.

Any advice?

Is the accessory circuit of the vehicle powered by the remote start? Asked a different way- when you remote start the vehicle, does the radio power up? If not, it needs to. I believe this should eliminate the conflict.

Yes, when I remote start the vehicle the radio powers on.

Under the OEM Setup > Gauges > OBD2 communication, try setting the communication to "Enabled On Demand".

Just tried that, no change.

I should also add that the OBDII connection has been unplugged.

I had a chance to do some additional testing today. I was able to interrupt the accessory wire feeding the radio & Meastro. By doing so I was able to start the vehicle. My issue is that I don't have a trigger to use to make this happen only when the remote start is active.

As we discussed last week on the phone the DB3 does not have a GWR output in RSR mode. Therefore you are going to need a standard remote start system in conjunction with the DB3 to provide that GWR output to trigger the radio ACC isolation relay needed to keep the radio from turning on during remote start. Looking at the install guides for the DB3 its not that much more complicated the the RSR install and you still can use your factory remote if that is why you went with the DB3 RSR to begin with.

I've removed the Maestro RR and replaced it with a different brand/product. Though I would have liked to have kept it, that fact that the Maestro interferes with another product is just silly to me.

Im sure it would be easy enough for your engineering dept to find a resolution rather than tell me I need to buy a different remote start to keep a radio interface.

FWIW I looked at the SW as well but for some reason your website wont let me configure one for my vehicle. :roll:

Let's be fair here- it's not entirely our fault that the two products conflict. It is just as much the remote start's fault as it is ours. Realistically speaking, auto manufacturers put a LOT of data on one line, and if more than one device tries to communicate on it, it is likely to make one of the devices fail. We offered a solution, you chose not to go that way, and ultimately lost the cool features the RR provides.

The SW is listed for your car, but it isn't the best solution for your vehicle, as your car has 3 steering wheel circuits, and the maestro SW is a more basic product that only supports 2 circuits. Because of that, you would lose the use 4 buttons on your wheel. The RR is capable of keeping all those buttons (and giving you much more); the SW is an option, but you would lose your Enter, Back, Left, and Right buttons.
