I got this new Ottonavi in October around the 26th 2012, and immediately had problems with GPS not finding the software I accidentally touched the SD card while trying to turn it off with knob while driving and it was so hot it blistered my finger.
I contacted Ottonavi thru email the following Monday after about a week with no response back I took the time off to call .
I had decided I would take the restock fee loss and call it quits since I had already got one and returned it to Amazon prior to this one Amazon accepted it back but it was not in stock and could not get a replacement and I got the impression they would not be getting them in again..
I called Ottonavi they said first to try making a new map the original sd card was probably bad they sent a link that took 2 days to download a new map their server is very slow like dial up speed. I have 10 gig download speed .
I made a new SD card map installed it and despite not being able to get the radio time and the GPS time in sync when the GPS displayed 12 hour with am and pm the radio displayed military 24 hour time and vice versa could not get them to sync.
Despite that it seemed to work ok in my driveway I was never quite sure since there were no instructions with it for install and the so called user manual was so poorly translated to English to read it and make sense of it besides being vague and it skipped around as if you are supposed to know how their unit is supposed to work it left me wondering WTF.
There were some wires labeled Speed I called Ottonavi support 2 times and neither guy that answered who barely spoke english could not tell me what they were for.
Then it messed up again so I contacted them wanting to return it for refund well it had gone past the 30 day after they jerked me around for almost 2 weeks now they will not accept it back for refund I am thinking attorney general route, and will only exchange it.
I returned it have proof of delivery was promised they would ship out a brand new unit the same day they get the old one back on their web page their policy is to ship a brand new unit when replacing , and promised to send the same day and provide tracking number when it shipped which I have not received and was promised again yesterday it would ship yesterday.
One other very annoying thing about it is that even the low setting for screen back light it is way too bright at night, makes it a bit dangerous, also there are listed choices of backgrounds and voices that do not have any program to operate it.
The key chime and door chime sound is very loud and I can't find a volume for it, like a sonar in a submarine real cheesy ear piercing crawl up your spine terrible noise and a very loud clock tic sound when turn signal is on, if I ever get one back I will relocate the speaker for it to some remote corner under the dash. Need I say I very much feel jerked around by Ottonavi just to get it out of refund period I clearly said I wanted to return it for refund the first time I called in and emailed because of my prior experience with one I got from Amazon and their lack of response? I have regrets of ever getting this unit. Just in case I ever do get the replacement does anyone know what the red speed wires are for and if there is a volume control for the door chime it does not use the factory chime and I do want it to chime in case I leave the lights on or something.
