I ordered 3.0 update and its coming tomorrow, but a neighbor who updated his 3.0 basically bricked his system and now Pioneer is gonna send him a replacement. If that happens to me, I am just going to buy a whole new system. I am actually quite unhappy with my 7010bt - its ok when it works, but just too damn buggy.

So my question is, what other NAV system could I get without re-wiring it? I have a rear camera, XM, HD radio. I dont care about HD radio.

Anyone have any suggestions?

well since you have the pioneer xm tuner you will have to get a pioneer to keep it working, the camera's are universal, as for the harness, maybe a D3 but there isn't a lot of options for pioneer navs, all of the F and X systems are going to have the same software based problems that you are experencing, some are less problematic than others
