Couls anybody help me to send me the schematic of this model or tell
me which is the type of this component?

That is a transistor...or regulator IC...or voltage inverter...it's very
hard to tell in surface mount parts these days. The component marked, 11S
X, right up over your arrow that's black, is a similar component case, but
not necessarily the component.

Because of its proximity to the filter coil above it and the big
electrolytic capacitor, I'd say it was probably power supply related. As
it is MELTED, we may assume its load is shorted, or way to heavy, in some
way. So, replacing this component will, probably, result in another melted
component just like it.

The little resistor at 5 o'clock from it also looks like it overheated.
The top towards the melted part looks discolored.

As to Garmin, I'm afraid I have a different opinion. My Garmin VHF walkie
got water inside its submersible case a few years back. Garmin sent me a
whole new unit, complete with all new accessories. They've sent my captain
a new Garmin 185 after his failed. They even paid the shipping on a UPS
pickup at my home. The 45 is awfully old, now. Garmin has no parts, I
assume, as it's way beyond its life expectancy. Your Chevy dealer has no
parts to fix your '66 Impala, either. Try to get a trim panel for your
1986 Sea Ray from your dealer, too. It cost a lot more than that little
GPS.
