I've decided to go with a bluetooth (or possibly wireless) OBD scanner & an android app instead of SG or UG. Does anybody have any experience, either good or bad, with one of these? There are a bunch of them out there, prices all over the place.
Here's 1 review I found:
ELM 327 OBD-II Bluetooth Scanner/Transmitter Review. That one can be bought for about $12
Here are some of the other options:
PLX Kiwi Bluetooth | OBD2 OBDII Android $53
ObdPros $85
ScanTool.net LLC - Scan Tools, PC, iPhone, & Android based OBD-II (OBD2) Interfaces, OBD diagnostic software $70
Cheap ELM327 Bluetooth OBD-II Wireless Transceiver Dongle $23.40
OBDII Bluetooth Car Diagnostic Cable - Black + Blue + Orange (DC 12V) - Free Shipping - DealExtreme $9.30
