The HFL feature doesn't work on my car, I press the button on the steering wheel and nothing. So I'm unable to pair my phone with the car. Plus given that it's Cal. traffic rule to use and handsfree method when driving, I would like this feature to work. I heard and read up about a technique of baking the board of the unit and it might revive it. I baked it and no results, so now I'll just pony up the money and buy a new unit, so beside Amazon, or eBay, where else should I be looking that has the best price and guarantee the unit is working.
