It will work , fine , the problem we see is the amount of time it takes to work . they seem to be slow , let us know how the 50 channel works mine along with most of the 07 and 08 only have 16 channels ? from what ive learned their is only 16 satalites , but the advantage you have is that with 50 channels it will switch to stronger signals for positioning . Please let us know how you like it.
