Hi, I'm a new member, but all the info here is great, since the Hualingan unit doesn't come with any installation info or guide

, I installed my unit and took me about 5 hrs....
I haven't figured out how to place the brackets, but I'll do that today, and haven't got my gps working the signal is very weak, I'll recheck the antenna today also, but software works good the Igo8 and polnav, destinator 9 crashes, it seems the unit has very low memory for this kind of softwares, a guy told me he can increase the memory, but I'll post that if I do.
Thanks for all the info, you guys have done a great job and the units look awesome installed, mine improved the sound like 40% with the same speakers, and one question what is the DSP they are talking about?
