Yes, this is an issue. There is a Dakota Digital box that can take a speed signal and spin a cable to drive the original speedometer, but you still need some kind of a road speed input and the TR6060 has nothing. Still noodling that whole deal.
I'm not a fan of GPS speedometers. They work great as long as there is a signal, and I doubt I would see an issue in my area unless I go down to the river. Pretty sure I would be blind to my speed then. And any trips over Highway 2 to Everett or even Leavenworth would be a pain. Just not a fan, but that's just me.
I understand. I wouldn't mind if my interior had a mostly stock look, but gauges are one that doesn't bother me beyond a full digital dash. I like dials myself.
I did figure out that the Speedhut Freedom CANBus gauges should work in my situation. Still don't have a way to put a speedometer code onto it yet, but it's a start.
