Dolphin gauge w gps 1950 AD
Has anyone used the Dolphin gauges with a gps speedometer? Was wondering if they had any problems, accuracy, does it calculate odometer also?

Re: Dolphin gauge w gps 1950 AD
I'm not finding a set of instructions but most GPS speedometer/odometers are pretty easy to set up and are spot on accurate.
You might have issues in tunnels, or in a city with tall buildings blocking the signal for a bit but other than that they work good. No issues with tire size changes or gear ratio changes. I have used my hand held GPS that I have for my boat, the dash mount car gps that I have had for years or my phone's GPS speedometer app in my ot truck as a speedometer since that truck's speedometer is broken. All work equally well except when there is actually something blocking the signal and the odometer functions seem to pick right back up and stay accurate. I know one guy who use the phone app speedometer to drive clear across the country and back last year. That said I don't really see an issue with the GPS speedometers and the best part is you don't have to fight with calibrating them like you do with a mechanical speedometer.

Re: Dolphin gauge w gps 1950 AD
I was actually kinda disappointed that Dolphin introduced their GPS speedo option just AFTER I bought my gauge set from them. I got the programmable electric, but if they'd had the GPS unit that would have been my first choice. Phone apps have almost rendered vehicle speedometers obsolete. I use one called DigiHUD - it works awesome, even tells me the speed limit of the road I'm on in case I can't see a sign.

On my Dakota gauges the odometer function has a little tab on it. The odometer doesn't start until you pull the tab out. It's nice for testing when building. Once you pull the tab out there is no looking back.

Thanks for the replies. Mick, are you talking about the model with the GPS?

On the dakota HDX all the extras are modular. Things like cruize, gps, boost or individual tire pressure are just separate modules that that you buy and plug in and they read on your main guage. I think there are 16 different one in all.

Re: Dolphin gauge w gps 1950 AD
four years ago I bought a set of new dolphins for my 1965 C10 - I was not happy at all. I don't think any of the five gauges were accurate. I would stay away from them. spend the extra$ and Go with dakota. Gauges are something that I would never cut cost on again.

Dolphin gauges are very sensitive to grounding requirements. Gauges and senders must have excellent grounds, ie no sealer on sender threads, no rusty dash rivets, etc etc.

I went crazy with new grounds everywhere so i know that was not the problem. Maybe I just got a bad set?

Re: Dolphin gauge w gps 1950 AD
On the Dakota the gps updates 10 times a second and has memory for when you lose signal. I'm guessing it's using the tach. One thing that sold me on dakota is that I don't have to buy everything at once. If I want to add outside temp and compass later I just buy the module and plug it in.
