Jim, Paul, dhjam1, Chris and Carl,
Sorry for the late reply. Had a looong weekend "amusing" with the car stereo and couldn't really find any decent time for WGT. I read and appreciate(d) all of your comments though. :-)
So... I looked around and found some more stores in my area. Unfortunately, none of them offered that free install deal. Guess not many know how to do bid'ness here. I went by Craig's rule*, decided to go with a guy who offered $150 for installation and made an appointment with him. (* The lowest offer being $80, the highest $200!)
I drove into his garage with the stereo, the guy checked it out, opened up the front panel in the vehicle and looked into it. Then he said he would do the job for $200 'cause he would have to cut off the bracket to make it fit. I said OK as I just wanted to get it over with instead of running around and looking for someone else although I was like "Extra 50 bucks for cutting two tiny pieces of metal??!!". A few minutes later, he said this time that I would have to buy "his" harness because otherwise he couldn't work on it. All together asking for $250! By this time I knew he was BS-ing me because I'd done my studies in case of DIY! I was so mad & frustrated, thinking "F*** it! I'll do it myself. The worst case scenario would be blowing 100 bucks." so I told him "Forget about it", went to Home Depot, got some tools and made my way home.
It took me hours and hours as I wasn't familiar with any of this, triple-checking everything, but I managed to get it done at the end of the day.
The double-din is practically an Android tablet sitting on the car-stereo place. Everything works fine fortunately and it looks OK as well.
I even tried WGT on it LOL and... nah, I won't be playing with it. The way the device responds to each tapping is too inconsistent. I think I hit ding only once. LOL
It will be useful for keeping CDP or watching free-credit videos, though...
Now the only concern is... how long it will last before it dies on me. *Fingers crossed*
Thanks for reading, guys. TTYL.
Simon
