Couldn't remember when we had it in for update in original post. Seems you misunderstood my summary of events by the way it was worded, however, the point is the fix didn't serve its purpose of fixing these units. In fact it was fine for a longer period before they messed with it and since problems every 2 months after so far. Seems to me they need to get their electronics engineers and programmers to sort these out or produce a new unit that doesn't suffer from this defect. If they want to waste their time and mine changing out one failed unit for another containing the unfixed defect until warranty runs out then fine by me. After warranty runs out though I'll be requesting they continue to fix their known to be defective units at no charge to me or provide a suitable working non manufacturers gps as the vehicle was sold to me with nav system and came with a warranty that it was free from any known defects and that any defects discovered during the warranty period would be repaired. As the defect has not as of yet been repaired I will push the responsibility back to them until they fix it properly.
