With my Palm Pre being the gateway to my audio content, I was growing tired of using a cable to hook it up to my Bluetooth-less vehicle. This was the cheapest solution for my needs (new car or new stereo are both too pricey today), as I wasn't expecting to take many calls...especially after hearing the reviews regarding the mic. Installation was pretty easy. I already had a ground loop isolator and it worked well with the LiquidAUX. One aspect of the installation was getting the remote to work. It seems that my unit needed to have the spring tension increased, so I lifted the spring (it was relatively flat) up a bit. Its been working ever since (a week now).
