davefj Posted January 17, 2008 Report Share Posted January 17, 2008 I just got the Z1 to Z2 upgrade off ebay, and every time I start my truck in the morning is say cannot use HDD. I have the 2 wire bypass, this will last for maybe 20 min or so I have to restart my truck over and over before it will load. Any idea of what this could be? thanks for any help Quote Link to post Share on other sites
tsiawd666 Posted January 18, 2008 Report Share Posted January 18, 2008 Completely wild guess, but perhaps it's too cold? What hard drive is it? I'm wondering what the operating temp specs are for it. Quote Link to post Share on other sites
dawgbone Posted January 18, 2008 Report Share Posted January 18, 2008 This is true...It can be too cold for it...I think the manual says that when it's too cold, it will not boot up until the cab comes up in temp...I also believe it says that it will still tune into radio(FM/AM) though... Otherwise, you may be dealing with a bad drive...Is the drive unlocked? Quote Link to post Share on other sites
whtcrxghst Posted January 18, 2008 Report Share Posted January 18, 2008 If you paid for a drive off ebay, I would send it back and ask for one that works Quote Link to post Share on other sites

mike35z Posted February 8, 2008 Report Share Posted February 8, 2008 Some of the people that are selling the Z1 upadate Hard drives are not using an automotive grade drive. The original HD used in the Z1 was built to higher specifictions. One of the specifications is the ability to run correctly in wide variences of temperature. The interior of a car or truck can often reach in excess of 130 degrees in summer and below zero temps in the winter. The hard drive is the main mechanical device used in the Z1 units. This places rigid specifications on the hard drive. The toshiba OEM drive was built for these tolerances. I have noticed that most of the Ebay replacmemnt drives are not a Toshiba automotive grade hd. Toshiba sells a 40 GB automotive hard drive that spins at 4200 rpm. MK4050GAC. The drives listed on ebay state they are 40 gb, and spin at 5200 or higher. These are not automotive grade drives manufactured by Toshiba. The Automotive hard drives are also about double in cost. The cheapest Tosheba 40gb hd, that is automotive specification, costs around 129 dollars or higher. The ebay replacment drives are standard laptop type hard drives, and will not perform the same as an automotive grade drive. I would suspect that is why your HD is not booting correctly. What can also happen is that these standard hard drives can become damaged from any rough vibration, especially during bootup, or in extreme temperature conditions. When the hard drive is first turned on, it reads files for booting up the system. If any of these files become damaged, booting can be delayed or not boot at all. If your going to replace the hard drive, be certian it is an automotive grade drive. I would suggest returning this drive for a refund if possible, and using the original drive with the Pioneer update disk, or purchase an automotive grade drive that has you update pre-installed. Toshiba is selling a new automotive grade hd (MK4050GAC), that is 40 gb and 4200rpm, with rugged specifications. Will be availabe in april of 2008. This is an excellent upgrade for the Avic Z1 unit. http://sdd.toshiba.com/main.aspx?Path=H ... ifications Quote Link to post Share on other sites
