Roadpro Digital Compass, Inside & Outside Temperature, Voltage Meter and Ice Alert

The compass is of great help as we're relatively new in the area. The temp. read out is a great asset. and as for the ice ice alertI'll wait a bit for that.(hopefully).

I recommend to everyone that does not already have a factory installed compass. It is easy to install and very simple to take down if nescessary.

The unit arrived promptly. I installed in my Ford Edge and it sits neatly on the console under the dash overhang. Upon powering it up, I noticed that the thermometer defaulted to celsius no problem all I had to was open the small battery door in the base and slide the switch to Farenheidt. I did that and everything seemed to work perfectly. The compass was easy to calibrate and matches the readings on my GPS. Upon powering off the unit and back on again, I discovered the temp reading reverted to celsius. Once again I opened the door in the base and moved the switch from F to C and to F again. The reading was F again but when powered off and back on, it reverts to C. If the switch position is F, the temp reading should stay F. Very disappointed in the shoddy workmanship of this unit.

I bought this for my wife's new Ford Escape because she missed having a temperature readout. This is a very accurate inside and outside thermometer and has 3 compass readouts. I installed it in the console, in less than an hour, instead of the dashboard to keep it out of the line of sight. The built in back lighting makes it easy to read day or night. The outdoor temperature sensor is long enough to run to the grill area and fresh air that is not contaminated by engine heat, which gives a more accurate reading. The voltage meter is useful for monitoring the battery condition. The car is driven short distances, which drains the battery in the winter weather.

I installed this on my 2006 Toyota Highlander after my wife complained that it didn't have a compass or outside temperature like our last car. Arrrgggghhhh! I purchased this for my wife for Christmas. It took a while to install it, as I mounted it in the middle of the dash just below the mirror and hid all the wires under the dash. Now that I have it up and running, I like the readability of the display. The compass and temperature seem to be pretty accurate. I have three negatives on the unit. First, after I mounted it I discovered that -even with the compass tilted as far forward on its mount as I could -it still slants backward about 15 degrees. I would prefer that it be straight, although it works well enough. Second, too much information is displayed. I really don't need battery voltage, but it came with the unit. Also, the compass shows the compass direction in three places including the psuedo compass card. Third, and the most serious, is that the unit causes noticeable interference on my CB radio. It's a pulse of noise that occurs approximately every second, regular as clockwork. The antenna is about ten feet away, mounted on the back of the vehicle. Shouldn't do that.

I did discover one idiosyncrasy. When I attempted the calibration, the unit wouldn't calibrate. It just kept on flashing the display in the calibration mode. I tried about ten times ... the whole while making the smallest circles I could in the car (the steering wheel was turned as far as it could turn it). Just out of curiosity, I did a large circle (about 100' in diameter). That worked like a charm -it calibrated the very first try. Out of curiosity, I tried to calibrate it again with the small circle -it didn't calibrate. I then did the large circle again and it calibrated just like it should. Go figure.

All said, I'm reasonably happy with the unit. I can easily read it from the driver's or passengers seat day or night. The compass is accurate and responsive. The out outside temperature is spot on. And the most significant benefit? I don't have to hear my wife complain about these any more!!!

I read up on every single on of these that is sold on Amazon, but i found this to be the one i thought would work the best. So i bought this for a present for my dad. And he loves it. It took a little install, he actually ran all the cords into his dash so you can't see them. These are two things we noticed about it.

Outside Temp: install the receiver out of the wind and far from the engine but somewhere in the front bumper works great. Also note the temp will not be accurate after you have been driving and you stop because of the engine temp. but once you start driving again it takes care of it.

Inside Temp: When you install the item on the dash when it is in the sun it is not accurate at all.

Enjoy.
