OBDII In truck scanner

I am interested in getting a in-truck scanner for my truck, mostly for checking mileage.

The 3 options I was looking at were...
https://www.scantool.net/obdlink-lxbt/ Scan Tool LX Bluetooth- $49.95

https://www.scantool.net/obdlink-mxwf/ Scan Tool MX WIFI- $79.95

ScanGauge SGEFFP Compact Multifunction Trip Computer with Customizable Real-Time Fuel Economy Digital Gauges (Frustration Free) , Black

http://www.amazon.com/ScanGauge-SGEFFP-Multifunction-Customizable-Frustration/dp/B00VX2NODO ScanGauge E- $94.95

I like the Bluetooth Scantool LX then use my phone, but I dont want to give up the ability to have my hands free phone calls in the truck. Can my phone do 2 Bluetooth things at once?
I would be fine with the WIFI Scan tool, but its only $15 less than the permanent option. I like that the permanent option lets me not use my phone, but means I cant transfer it easily to another car.

Any advise or first hand knowledge on any of the options?

 

What about the Ultragauge?

 

I didn't see see an option for a Tacoma?

 

What do you mean, I have an Ultragauge in my Tacoma.

 

How does it work? What all does it show ?
What one do you have?

 

Plugs in to the OBDII input and has tons of options. Go on Ultragauge.com and check it out.

 

How accurate is the gas mileage?

 

Pretty accurate. Even better if you tune it after 3-4 fillups.

Right out of the box, my SGII was within a mile/ gallon.

I've tried the Bluetooth with my phone unit. I like the stand alone units better.

 

Once calibrated I find it to be very accurate

 

I saw it and like parts of it. I like the features and price, but not really the size/shape. If I did the permanent scangauge it is wide and short. I was planning on mounting it to rhe top of the mirror and running the wire behind the A-pillar.
I don't want to mount the ultra gauge on the window mount as I already have my GPS in my windshield and would prefere to not block more of my road view.
How do you have yours mounted? Any pics?

 

Mine is mounted on top of the dash next to my GPS

 

A common place to mount a UG is above the mirror. That's where mine is. Just route the cable through the liner and down the pillar. I used an old bicycle reflector mount to mount it direct to my mirror. I highly recommend it.

 

Would you mind snapping a pic of it from the drivers view and the actual mount? When I was looking at it online it just seemed so much bigger than the scangauge.
Also how long is the wire? I know the scangauge says 6'. I was wondering if I would have to cut the wire and splice in a foot or 2 behind the dash or somewhere.

 

I would love to, but unfortunately I'm out of town for work until the 22nd. I got the idea for mounting from a thread around here showing different mounting locations (search for it?). The cable is JUST long enough to make it without splicing. No need to drop the headliner either. I only had to pop off the cover for the pillar as I was able to tuck it into the headliner then fish it through the dash with the fuse panel cover off.

Edit: Just google image search "Ultra-gauge Tacoma" for a good idea of the size and some locations.

Edit #2: It looks very close to this in placement:

 

Does that one show transmission temp ?

 

Can someone clarify, if you put bigger tires without regearing, an odb2 scanner is going to be reporting mpg, mph, distance travled, etc inaccuratly. Am i correct?

 

With the ultra gauge you can calibrate it to fix that.

 

Don't get the OBDLink dongles. I have one, and it gives me connection issues constantly. Do some research and you will find that a lot of people have had issues with these damn things. I had a $12 ebay special for years that worked very well, but I traded it with a friend for the OBDLink. Really bad move

 

Thanks. I seemed to think it was much larger. That looks decent. Tucked up out of your field of view, but still easily viewable.

 

I had the same misconception. When I opened the box I was pleasantly surprised. Above the mirror is a very clean install, one in which most people don't even realize it's there and it's hard to see from the outside.
