Another satisfied customer of Garret Toomey's. I purchased his 60g hard drive with the Z3 maps on a Saturday and I received it the next business day. Start to finish was fifteen minutes to swap out my Z2 drive. Everything works perfectly. I would highly recommend Garret's HD vs. Pioneer's 3-4 hour DVD upgrade. For the same price as the DVD's, you get a 60g hard drive, Z3 maps, tools, instructions and all the questions you may have answered by Garret. I would not hesitate to purchase from him again. He answered all my questions within hours (sometimes minutes). Try that with Pioneer customer se
