It's not diffucult to put and aftermarket indash in an H2. If your local stereo shop say they can't or won't do it then they should find a different business to be in. You need a mounting kit a wire harness and an antenna adapter. Here's the deal though. The wiring harness will not be cheap. And you have to figure out what you want to keep and/ or what you can do without. Do you have Bose? Do you want to keep the Bose? Do you have onstar? Do you want to keep onstar? Do you have steering wheel controls? Do you want to keep the wheel controls. Do you have Sat. Radio? Do you want Sat radio? You can keep everything except the OEM Sat radio. But you can add it to your aftermarket unit. Along with Reverse camera, Bluetooth, Ipod control, etc. Depending on what you have and want to keep will make the install take more or less time. You can find the parts you need from places like: Aamp of America, PAC, I Simple, Metra, Best Kits. The best thing to do is lose the Bose amp, but you will lose onstar. The easiest is to keep Bose and and Onstar.
