Bests & Worsts Reviews from Amazon

Bought it in April and now I'm on unit # 4! Garmin's acknowledgment is below. THESE UNITS consistently loose the voice. When this happens it still navigates but the system starts to hang. Also the navigation will start to hang too if you alter your route. You need to shut off the unit and restart but then it will soon happen again. The 1st replacement was a refurbished after they promised me a new unit. With the 2nd replacement, just like the first one, I made sure that not only did I have the most recent map but also that I had all the unit updates. On the 3rd replacement that I received yesterday I didn't update it and sure enough the same problems occur. I have spoken to Garmin by phone about 8 times since May and many e-mails. I just contacted Amazon and someone at Garmin Corporate, I'm waiting to hear back. I'm just amazed that Garmin is still selling this unit, why don't they recall these? Here is an e-mail from a Garmin support Tech from over two weeks ago: "Unfortunately, there has been an issue with the latest software update on these units. Our engineers are working on an update to correct this issue, and we expect to see this very soon. Your account is set up so that you will receive an email notification when the update is available, but you are more than welcome to email me if you do not hear about this soon."
