Garmin ecoRoute HD and Android = gauges/code reader for $100
I picked up a new GPS recently and also bought the ecoRoute HD module that is a Bluetooth module that plugs into the OBDII port and it gives you the option to show coolant temp, voltage and about 7 or 8 other options for a gauge readout. Some are kinda useless though, I mainly wanted those two. On the GPS you can pick from showing 5 different gauges. This is how I had mine setup the other day.....

That temp was while my car was still warming up, normal operating temp is right around 200-205.
Now about Android....if you have an Android phone you can just buy the ecoRoute HD module for $100 and download the Garmin Mechanic app and it works similar to how it does on the GPS. It looks though like you can only pick 3 gauges to show at a time. It also works as a code reader and can reset a Check Engine light. There's even a few options on the Android app that I can't do like a shift light and rev limit light and check 0-60mph and 1/4 mile times. Also, on both versions there is a nice current MPG readout that also shows fuel used and cost.

Same GPS unit at Amazon.com (and cheaper).
.......pretty slick unit but some of the things about how it operates make me wish I had my big old Garmin back. They've dumbed down their GPSs in recent years, I had more setting options on my old one. I'm still debating if I am going to keep it or not but there's no doubt the gauges readout is great to have. I wish I had an Android phone now then all I would need is the $100 ecoRoute HD module.
