Garmin/Apollo Mx20 moving map
 

Does anyone here have any experience of using an MX20 moving map?

We have on in our aircraft and are looking to update the moving map so that it shows more topographical information i.e. roads and rivers etc.

I have tried getting intouch with Garmin in the UK but only seem to get their general enquiries number and get through to someone who has never heard of an MX20!

Does anyone know contact info for Garmin in the UK about aviation GPS's? Their website doesn't really specifiy aviation contact details.

Any help appreciated.
