# Silly Garmin

attached is a photo of my Garmin showing an unbelievable speed, photo was taken on a recent trip to Arizona, I might have been near Roswell NM?

I asked if he had taken it on an airplane or something, but he hadn't; just normal driving. He said it was after driving about 2500 km.

It's just a funny photo he wanted to share...

### GARMIN must not know

### Hmm

 Hmmmmmm, I was trying to come up with ideas for a too-high maximum speed as I think there are ways this can occur other than actually traveling that fast in a plane, etc. But when I saw the two average speeds, I realized that Garmin on that trip was truly silly since there's no mathematical way average speeds can be higher than the maximum speed. I do note that the owner must be from outside the USA since the device is set to metric even when traveling in the US. Then again, maybe it occurred five days ago and was a display of the unadvertised Garmin April Fool feature offered on some new GPS models.

### I want that car!

 I want that car! Just Sayin!

 I know there is a multiplier for converting US Dollars to Canadian Dollars. Is there a similar multiplier for converting standard KMH to Canadian KMH as well???

### As far as I know, KMH is KMH

 As far as I know, KMH is KMH no matter where you are. Or did you mean MPH to KMH? A rough rule of thumb is 6 x KMH /10. Or 10 x MPH / 6. 60 MPH x 10=600 / 6 =100KMH. 100KMH x 6= 600 /10 = 60MPH. It's not exact, but it will keep you from getting a ticket.

For those really anal folks the exact conversion is: 60 MPH eguals 96.56064 KM per hour 100 KMH equals 62.137119 MPH As phranc says, just doing the 6 thing will keep you from getting a ticket.

### I have often wondered why it is not possible to ...

 ... permanently turn off the trip log (on Nuvi 1450/2555), and why clearing the trip log will sometimes leave all sorts of trip debris, sometimes going back a couple yrs.

### Set you GPS.

Or set your GPS to MPH or KPH depends what country you are in.

### My husband

 My 74 year old husband is still just a kid. The other day he got our 2014 6 cly Honda Accord up to 110 mph. I didn't have my Nuvi but wish I did. Needless to say I was not happy with him. It was a little scary and I was (not softly) telling him to slow down...

### Yup

 Or set your GPS to MPH or KPH depends what country you are in. Exactly what I do!

### it would be nice

 It would be nice i the unit would do the switch automagically. It could be done by setting coordinates much like they do for time zones and daylight saving times.

### Too high a maximum speed typical for me

 I believe every Garmin I've used has shown a too high maximum speed, except for the 3597. Even my 76csx showed me hiking at a speed I could only achieve if being pursued by bear. Don't think I've ever had one show an average greater than the maximum though.

### I'm seeing 140 km/h max

 I'm seeing 140 km/h max speed and 116 km/h current speed. That's about 88 mph (max speed) and 73 mph. I don't get it. What's so unbelievable? Max speed on an airplane would've been 500+ mph or 800+ km/h.

 lol

### Look at the two average speeds

### Thanks

 I guess I was thinking "distance travelled" when I saw those two AVG speed. Didn't pay attention to the units (km/h).

 I was going to say, I hope he had a radar detector, but at those speeds, you don't need one! Heh.

 Let's assume the trip info was reset when he started. Driver says he went about 2500km and we see he was traveling 116km (72mph) at the time he took the picture. That suggests he drove for around 21 hours if 116kmh was reflective of his average speed which seems reasonable. So if the times are in minutes and seconds, if you add 1000 to the moving time you get 1118:59 minutes which is ~18.65 hrs and is in the ballpark of the estimate above. So maybe the GPS lost track of the 1000 like when an odometer rolls over so it used the time it had which was only 118:59 (or 132:33) to calculate the averages. This caused the average rates to be ~9x too high due to the lost 1000 minutes in both time categories.
