I've had a PNI compass for about 3-4 years now in my Taco. I'm NOT impressed and don't feel it worth the $$ unless you 100% must have a compass. Its way to inaccurate to help establish landmarks in the backcourty. It might be fine for highway/street use, where roads signs will help you navigate, maybe like an RV.
I called PNI and asked how to fix this, I was told it is normal, and PNI is very happy with their product, even if I wasn't. When I called they said I was talking to their engineer, and I tried to discuss an easy fix, but they where NOT interested.
Since I have more than one navigation aide in my truck, I have learned to deal with the PNI compass. BUT in my opinion you are better off with a cheap $5 to $15 handheld pocket compass if you are trying to navigate around the backcourty. If you want an in-out temp gauge, there are much better units for alot less $$s
I have a few friends who also got the PNI electronic digital compass and feel it was money mis-spent for navigation. Also the suction cup design is very poor and will need to be reworked or completely modifiyed after about 2 to 3 years. A friends mount clamp broke and after contacting PNI, was told the part was not available, he would need a whole new compass, so I made him a home-made support bracket.
Other than that the compass I have is nice, the buttons are easy to use, the dual power is handy, and the auto-back lite is useful.
