    Frage Roadrover C7086P2 no GPS signal

    The unit came with 4Gb SDHC card with iGO 8.3 installed. The problem is, I can't get a GPS fix. When parked outside, this is what I got [Only members can see the link] and after driving around [Only members can see the link] but no GPS fix. To rule out faulty antenna, I bought another but It didn't help. Infact removing the antenna has no effect at all [Only members can see the link]. I have measured the antenna port and got 3.27Volts, so thats not it.

    I have used SirfTech to get GPS port and im pretty sure its "1" [Only members can see the link]. Baudrate is not so clear, I get NMEA messages with all baudrates. I used SirfTech to test other baudrates, but it had no affect. Currently the baudrate is set to 57600. When I launch SirfTech, I get GetCommProperties 1 & 2 error with boxed characters, Chinese I guess?

    I got the unit from FeDom and they have suggested to send me another gps module. To me, it looks more like a software/firmware problem.

    Here's information from my unit. What does the "AS-" mean in OS version, Asian market? Can I update It?

    Other than this, the trip computer data have been updating in realtime only ONCE I've had the unit this past week. If I leave the MP3 player playing when turning off the car, 9/10 times OEM audio stalk control wont be working next time I start the car. Obviously the MP3 player doesnt have usable fast forward function and the stalk cannot be used to fast forward MP3 (is there fix for this?). Audio CD player is using the DVD function, so I have black screen when driving and listening CD, this can be fixed, but the DVD player software is still really bad for listening audio CDs.

    I've managed to update the Shell and OS.

    Now COM1 is "virtalSerial1" and COM8 is GPS. Both give me NMEA data with all baud rates.

    I've noticed that latitude, longitude and altitude reported by SirfTech are wrong and DOP is always 60. Obviously I get no GPS fix even though GPS Viewer gives me 12 satellites in view.

    You have taken the WRONG OS. Your unit C7086P2 has 128MB RAM, not 256MB !!!!!
    You must run a second update and replace by OS "EN-PRIMA-V1.53-60Hz":

    Which tool did you use to show the COM Ports ?

    I'm quite sure the system has 256Mb of RAM.

    COM ports are from SirfTech

    It's starting to look like it's the GPS module. Cold starting doesn't work at all. NMEA messages stay 00000 even after driving around for nearly 2h. Hot start puts me nearly 1500km off somewhere in Russia, no fix that far off. Factory reset doesn't do anything.

    I've been waiting for over a month the promised new GPS module and Im getting frustrated Does anyone know what kind of GPS modules RoadRover use?
